Gas-phase thermolysis of condensed-1,2,4-triazines: interesting routes toward heterocyclic ring systems

Gas-phase thermolysis of thieno[2,3-e][1,2,4]triazines gave benzonitrile, isothiazole, pyridazine, and thieno[2,3-d]thiazole derivatives. Similar transformation of benzo[1,2,4]triazine and phenanthro[9,10-e][1,2,4]triazine derivatives into their corresponding condensed thiazoles has been achieved by heating at 350 degrees C with sulfur. A mechanism for these pyrolytic transformations was proposed. (c) 2007 Published by Elsevier Ltd.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 1896-62-4, in my other articles.

Microwave-assisted novel and efficient one-pot synthesis of fused steroidal and non-steroidal isothiazoles

efficient microwave promoted one-pot synthesis of steroidal and non-steroidal isothiazole derivatives from corresponding beta-bromo-alpha,beta-unsaturated aldehydes has been described using a sodium thiocyanateurea system. The beta-bromo-alpha,beta-unsaturated aldehydes derivatives are efficiently synthesized from corresponding cyclic ketones using Vilsmeir formylation reaction. The synthetic protocol is also applied for the synthesis of antifungal brassilexin. (c) 2012 Elsevier Ltd. All rights reserved.

Theoretical Calculation of Thermodynamic and Kinetic Quantities for 1,3 Dipolar Cycloaddition Reactions Between Nitrile Sulfides R-CNS (R = H, CH3, Ph and Ph(CH3)(3)) with 7-10 Membered Simple Cycloalkynes

The 1,3-dipolar cycloaddition reactions also known as the Huisgen cycloaddition are one of the most widely used and versatile preparative methods in hetro-cyclic chemistry. In this study, the reactivity and strain energy effect of the simple cycloalkynes with substituted Nitrile sulfides R-CNS (R = H, CH3, Ph and Ph(CH3)(3)) will be discussed in light of computational studies using DFT methods (B3LYP/6-31G*). The investigation of the structured properties, theoretical thermodynamic and kinetic data of the reactions in 298 K will be presented. The results show increase in the Delta G* by increasing the ring size and decreasing the strain energy of cycloalkynes. Also, the rate constants and the free energy changes in reactions increase as the size of the ring decreases. The relationships of the deviation of the internal bond angle (DIBA, in degrees), pi-strain (S pi) (in kcal mol(-1)), the bond angle of Csp(3)-C C (theta degrees) and Delta G(#)(kcal mol(-1)) for the series of cycloalkynes I-1 to I-4 have investigated.

A new monoclinic polymorph of 3-diethylamino-4-(4-methoxyphenyl)-1,1-dioxo-4H-1 lambda 6,2-thiazete-4-carbonitrile

A new monoclinic form of the title compound, C14H17N3O3S, has been found upon slow crystallization from water. Another monoclinic form of the compound was obtained previously from a mixture of dichloromethane and diethyl ether [Clerici et al. (2002). Tetrahedron, 58, 5173-5178]. Both phases crystallize in space group P2(1)/n with one molecule in the asymmetric unit. The formally single exocyclic C-N bond that connects the -NEt2 unit with the thiazete ring is considerably shorter than the adjacent, formally double, endocyclic C=N bond. This is likely to be due to the extended conjugated system between the electron-donor diethylammine fragment and the electron-withdrawing sulfonyl group. In the newly discovered polymorph, the methoxy group is rotated by almost 180 degrees around the phenyl-OCH3 bond, resulting in a different molecular conformation.

Antidermatophytic activity of pyrazolo[3,4-c]isothiazoles: a preliminary approach on 4-chlorophenyl derivative for evaluation of mutagenic and clastogenic effects on bacteria and human chromosomes in vitro

The antifungal activity of eight pyrazolo[3,4-c]isothiazole derivatives was evaluated on five dermatophytes: three were of an anthropophilic species (i.e., Epidermophyton floccosum, Trichophyton rubrum, and Trichophyton tonsurans) and two were of a geophilic species (i.e., Microsporum gypseum and Nannizzia cajetani). The new compounds proved to be unlikely effective in inhibiting the growth of the different strains. In general, the fungi parasitic on man were more sensitive than the geophilic species. This fact can be positive for a possible practical-therapeutic utilization of this class of compounds. To verify their possible use against fungi of medical interest, the most interesting substance at low doses, 6-(4-chlorophenyl)-4-methyl-6H-pyrazolo[3,4-c]isothiazol-3-amine, was chosen to perform in vitro genotoxicity tests using the following: Salmonella/microsome test (SAL), sister chromatid excange test (SCE), cytokinesis-blocked micronucleus test (CBMN), and its improvement (Ara-C/CBMN). The compound showed no mutagenic activity at low doses, whereas at the highest dose (100 mu g/mL), it caused a generalized cytotoxic effect. The high growth inhibition exerted on fungi at the lowest dose and the concomitant lack of genotoxicity, at least until the dose of 50 mu g/mL, might suggest the compound as a safe candidate as an antidermatophytic substance.

The crystal belongs to triclinic, space group P (1) over bar with a = 4.6395(15), b = 8.689(3) angstrom, c = 17.917(7) angstrom, alpha = 87.763(9), beta = 84.625(9), gamma = 82.344 (9)degrees, V = 712.4(4) angstrom(3), Z = 2, D-c = 1.465 Mg.m(-3), lambda(MoKa) = 0.71073 angstrom, F(000) = 328, mu(MoKa) = 0.242 mm(-1), the final R = 0.038 and wR = 0.089. A total of 3702 unique reflections were collected, of which 2762 with I > 2 sigma(I) were observed. X-ray analysis revealed that the benzisothiazolone ring and benzene moieties were essentially planar, and three intramolecular hydrogen bonds N(2)-H(2N)center dot center dot center dot O(1), N(2)-H(2N)center dot center dot center dot O(3) and C(10)-H(10)center dot center dot center dot O(2) were observed.
