Ir-catalyzed cascade dehydrogenative CH/BH and BH/OH cross-coupling of carboranyl carboxylic acid with readily available benzoic acid has been achieved, leading to the facile synthesis of previously unavailable carborano-coumarin in a simple one-pot process. Two cage B-H, one aryl C-H and one O-H bonds are activated to construct efficiently new B-C and B-O bonds. The cascade cyclization can stop at the first B-H/C-H cross-coupling step by tuning the reaction conditions, resulting in a series of alpha-carboranyl benzoic acid and aryl carborane derivatives. Control experiments indicate that B-H/C-H dehydrocoupling proceeds preferentially over B-H/O-H dehydrocoupling, and both directing groups and oxidants are crucial for this reaction. An iridium(V) intermediate is proposed to be involved in the catalytic cycle.

A multicomponent one-pot atom-economic reaction is performed for an efficient synthesis of 1-amidoalkyl-2-naphthol from aromatic aldehydes, beta-naphthol and amide/urea promoted by hexachlorocyclotriphosphazene (HCCP). Various techniques such as stirring, microwave irradiation and thermal technique (hot plate and oil bath) were used in different solvents for the synthesis of 1-amidoalkyl-2-naphthol derivatives with moderate to excellent yield. Among the four methods, microwave irradiation and oil bath heating provide high yield as compared to the hot plate heating and stirring method. The low yield may be due to the formation of undesired side-products due to non-uniform heating.

Endeavor to discover biorational natural products-based insecticides, two series (27) of novel 9R/S-acyloxy derivatives of cinchonidine and cinchonine were prepared and assessed for their insecticidal activity against Mythimna separata in vivo by the leaf-dipping method at 1 mg/mL. Among all the compounds, especially derivatives 6l and 6o exhibited the best insecticidal activity with final mortality rates of 75.0% and 71.4%, respectively. Overall, a free 9-hydroxyl group is not a prerequisite for insecticidal activity and C9-substitution is well tolerated; the configuration of C8/9 position is important for insecticidal activity, and 9S-configuration is optimal; 6′-OCH3 moiety is not necessary, removal of it is also acceptable.

Recently I am researching about ENANTIOSELECTIVE SYNTHESIS; DISCOVERY, Saw an article supported by the University of HyderabadUniversity of Hyderabad; SERBDepartment of Science & Technology (India)Science Engineering Research Board (SERB), India [EMR/2016/003801]; UGC-SAP-DRS-1. Published in ACADEMIC PRESS INC ELSEVIER SCIENCE in SAN DIEGO ,Authors: Jangir, N; Padhi, SK. The CAS is 93-02-7. Through research, I have a further understanding and discovery of 2,5-Dimethoxybenzaldehyde. HPLC of Formula: C9H10O3

Hydroxynitrile lyase (HNL) catalyzed enantioselective C-C bond formation is an efficient approach to synthesize chiral cyanohydrins which are important building blocks in the synthesis of a number of fine chemicals, agrochemicals and pharmaceuticals. Immobilization of HNL is known to provide robustness, reusability and in some cases also enhances activity and selectivity. We optimized the preparation of immobilization of Baliospermium montanum HNL (BmHNL) by cross linking enzyme aggregate (CLEA) method and characterized it by SEM. Optimization of biocatalytic parameters was performed to obtain highest % conversion and ee of (S)-mandelonitrile from benzaldehyde using CLEA-BmHNL. The optimized reaction parameters were: 20 min of reaction time, 7 U of CLEA-BmHNL, 1.2 mM substrate, and 300 mM citrate buffer pH 4.2, that synthesized (S)-mandelonitrile in 99% ee and 60% conversion. Addition of organic solvent in CLEA-BmHNL biocatalysis did not improve in % ee or conversion of product unlike other CLEA-HNLs. CLEA-BmHNL could be successfully reused for eight consecutive cycles without loss of conversion or product formation and five cycles with a little loss in enantioselectivity. Eleven different chiral cyanohydrins were synthesized under optimal biocatalytic conditions in up to 99% ee and 59% conversion, however the % conversion and ee varied for different products. CLEA-BmHNL has improved the enantioselectivity of (S)mandelonitrile synthesis compared to the use of purified BmHNL. Nine aldehydes not tested earlier with BmHNL were converted into their corresponding (S)-cyanohydrins for the first time using CLEA-BmHNL. Among the eleven (S)-cyanohydrins syntheses reported here, eight of them have not been synthesized by any CLEA-HNL. Overall, this study showed preparation, characterization of a stable, robust and recyclable biocatalyst i.e. CLEA-BmHNL and its biocatalytic application in the synthesis of different (S)-aromatic cyanohydrins.

The coordination of biologically active moieties to the axial positions of Pt(IV) derivatives of Pt(II) anticancer drugs allows the co-delivery and simultaneous activation of two pro-drugs for combination therapy. Pt(IV) complexes with a redox modulator as an axial ligand can kill cancer cells by a mechanism combining DNA platination and generation of oxidative stress. In this study we evaluated the cytotoxicity of Pt(IV) complexes based on the oxaliplatin scaffold and the pro-oxidant indole-3-propionate in cisplatin-sensitive and cisplatin-resistant ovarian cancer cells. A series of five complexes was synthesized and characterized by H-1 and Pt-195 NMR spectroscopy, IR spectroscopy, mass spectrometry and elemental analysis; trans-[Pt(DACH)(ox)(IPA)(OH)] (1), trans-[Pt(DACH)(ox)(IPA)(2)] (2), trans-[Pt(DACH)(ox)(IPA)(bz)] (3), trans-[Pt(DACH)(ox)(IPA)(suc)] (4), and trans-[Pt(DACH)(ox)(IPA)(ac)] (5) (DACH = 1,2-diaminocyclohexane (1R, 2R)-(-), ox = oxalate, IPA = indole 3-propionate, bz = benzoate, suc = succinate and ac = acetate). The complexes were shown to produce cellular reactive oxygen species (ROS) in a time-dependent manner. The most potent ROS producer, complex 1, also elicited the highest cytotoxicity. Complex 1 was shown to form the mono-and bis-adducts [Pt(DACH)(guanosine)( OH)](+) and [Pt(DACH)(guanosine)(2)](2+) in the presence of ascorbic acid, suggesting that on activation the released oxaliplatin will interact with DNA.
