A series of substituted 5-chloro-2-arylbenzo[d]thiazoles were synthesized using 4-chloro-2-aminothiophenol and aromatic aldehydes in the presence of urea nitrate as a catalyst using the mechanochemical grindstone technique. This protocol was effectively carried out under metal-free conditions at room temperature, and the desired products were obtained in high to excellent yields in short reaction time (30-60 s). The structure of all the synthesized derivatives was confirmed by spectral characterization. The designed protocol has several benefits like eco-friendly, solvent-free, high yields, easy workup, and recyclability of catalyst. The catalyst was reusable at least four times without significant loss of activity. The good functional group tolerance with a series of derivatives has been demonstrated.

A simple and efficient cascade reaction via formal [1+2+3] cyclization of 1,3-indanedione, aldehyde and 2-naphthol is reported using K2CO3 as a base. The advantage includes metal-free conditions, varied substrate scope and shortened reaction duration with high diastereoselectivity (i. e., 99 : 1) resulting in the formation of two carbon-carbon as well as two carbon-oxygen bonds through Knoevenagel-Friedel-Crafts-Hemiketalization sequence resulting in three contiguous stereocenters.

The design and synthesis of highly decorated cage [4.3.2] propellanes and D-3-trishomocubanes have been reported via ring-closing metathesis (RCM), [4 + 2] cycloaddition and acid-catalyzed rearrangement as key steps. These cage polycycles were prepared starting with inexpensive synthons such as 2,5-dimethoxybenzaldehyde and endo-dicyclopentadiene. Propellanes containing fused spiro[4.4]nonane ring system was realized by RCM protocol. Interestingly, the dimethoxy cage propellane derivative was observed instead of the rearranged product with Lewis acid such as BF3 center dot MeOH. Several intricate cage structures were synthesized from rearrangement approach that are difficult to generate by conventional routes.

A novel, quick, environmentally safe, and one-pot synthesis of a series of N,N-bis(cyanoacetyl)hydrazine derivatives, bis-imino-2H-chromenes and bis-2-oxo-2H-chromene derivatives have been designed. Some selected newly synthesized compounds were investigated in vitro for their antibacterial activity. Compound 5j is the most toxic compound against Staphylococcus aureus with activity index 171%, followed by compound 15b with activity index 136% compared to standard drug ampicillin. Moreover, compound 15a is the most toxic compound against Escherichia coli with activity index 111% compared to standard drug gentamicin. Minimum inhibitory concentration (MIC) was carried out for compounds with high antibacterial activity. Compound 5j has good MIC (7.8 mu g/ml) against Staphylococcus aureus while 15a has good MIC (31.25 mu g/ml) against Streptococcus mutans which is better than MIC of the standard drug ampicillin (MIC = 62.5 mu g/ml). Compounds 5j, 5k, 15a, 15b and 15e which have good MIC values were introduced to enzyme assay against DNA gyrase and topoisomerase IV. The results showed that compound 15a can strongly inhibit DNA gyrase and topoisomerase IV (IC50 = 27.30 and 25.52 mu M respectively), compared to methotrexate as the standard drug (IC50 = 29.01 and 23.55 mu M respectively). Structure-activity relationships were also discussed based on the biological and docking simulation results.

I found the field of Chemistry very interesting. Saw the article Scalable Wolff-Kishner Reductions in Extreme Process Windows Using a Silicon Carbide Flow Reactor published in 2019.0. Product Details of 93-02-7, Reprint Addresses Dallinger, D; Kappe, CO (corresponding author), Res Ctr Pharmaceut Engn GmbH RCPE, Ctr Continuous Flow Synth & Proc CCFLOW, Inffeldgasse 13, A-8010 Graz, Austria.; Dallinger, D; Kappe, CO (corresponding author), Karl Franzens Univ Graz, NAWI Graz, Inst Chem, Heinrichstr 28, A-8010 Graz, Austria.. The CAS is 93-02-7. Through research, I have a further understanding and discovery of 2,5-Dimethoxybenzaldehyde

A safe and scalable continuous flow strategy for Wolff-Kishner reductions that employs methanol as the solvent has been developed. The use of low-cost hydrazine as the reducing agent in combination with a caustic base provides an atom-efficient, environmentally friendly method for the deoxygenation of aldehydes and ketones to alkanes. Because of the required harsh and corrosive reaction conditions (200 degrees C, 50 bar), reactor materials such as stainless steel, glass, or any type of polymer have compatibility problems, rendering this process problematic on a production scale. The use of corrosion-resistant silicon carbide (SiC) as the reactor material opens up the possibility of performing Wolff-Kishner reductions on scale with a considerably improved safety profile. Methanol as the solvent significantly simplifies the workup procedure compared with the generally employed high-boiling solvents such as diethylene glycol. The continuous flow protocol was applied to a number of substrates and provided the desired products in good to high yields with space-time yields of up to 152 g L(-1)h(-1). In addition, a pharmaceutically valuable active pharmaceutical ingredient precursor was synthesized by employing this high-temperature/pressure Wolff-Kishner protocol.

A multicomponent diversity-oriented synthesis of new highly emissive tetracyclic isoquinolines that target specific organelles is described. The title compounds were prepared via a three-step protocol starting with an Ugi four-component reaction, followed by either an intramolecular alkyne hydroarylation and subsequent alkene isomerization or through a Pomeranz-Fritsch-type cyclization with a final intramolecular Heck reaction. Subcellular localization studies of these compounds using green channel confocal microscopy revealed remarkable and distinctive distribution patterns in live cells, showing an unprecedented high selectivity and imaging contrast. The differentiated organelle visualization-including localizers for mitochondria, lysosomes, Golgi apparatus, endoplasmic reticulum, and plasma membrane was achieved by varying the nature of the tetracyclic system and substituent pattern, changing the original four-component set in the starting Ugi reaction.

Name: 2,5-Dimethoxybenzaldehyde. I found the field of Chemistry very interesting. Saw the article Pyridine-2-carboxylic acid as an effectual catalyst for rapid multi-component synthesis of pyrazolo[3,4-b]quinolinones published in 2020.0, Reprint Addresses Patel, HM (corresponding author), Sardar Patel Univ, Dept Chem, Univ Campus, Vallabh Vidyanagar 388120, Gujarat, India.. The CAS is 93-02-7. Through research, I have a further understanding and discovery of 2,5-Dimethoxybenzaldehyde.

Green synthesis of pyrazolo[3,4-b]quinolinones was designed using bioproduct pyridine-2-carboxylic acid (P2CA) as a green and efficient catalyst. The multi-component reaction of aldehydes, 1,3-cyclodiones and 5-amino-1-phenyl-pyrazoles regioselectively produced pyrazolo[3,4-b]quinolinones in excellent yield (84-98%). Recyclization of the catalyst was also investigated. The electronic effect of the various substituents in aromatic rings indicated that the reaction proceeded through the carbocation intermediate. This newly designed protocol very quickly constructed products conventionally under milder conditions.

Synthetic studies on palmarumycin C-6 with a naphthyl acetal at the C-3 position in 4,7-dihydroxy-1-indanone as a lower homologue of spirobisnaphthalenes are described herein. We investigated three approaches: 1) Nazarov cyclization of benzoylketene acetal, 2) intramolecular Friedel-Crafts acylation of naphtho[1,8-de]-1,3-dioxin-2-aryl-2-acetic acid chloride, and 3) double oxa-Michael addition of 1,8-dihydroxynaphthalene to 3-bromo-l-indenone. The last approach successfully afforded the natural product after the removal of acetates that serve as protecting groups for phenolic hydroxyls under acidic conditions.
