Dehydrogenative and decarboxylative C-H alkynylation of heteroarenes catalyzed by Pd(II)-carbene complex

The direct alkynylation of heteroarenes was accomplished with easily prepared Pd(II) carbene complex (Pd Cat.) by two complementary strategies. Pd Cat. catalysed cross-dehydrogenative coupling of terminal alkynes with heteroarenes was achieved in the first method and decarboxylative coupling of aryl propiolic acids with heteroarenes was investigated in the second method. Both the methodologies tolerate a broad variety of heteroarenes that include benzoxazoles, benzothiazoles, imidazole and benzimidazoles.

Synthesis and screening of some novel N-(4-Oxo-2-substituted phenyl- 1,3-thiazolidin-3-Yl)-1,3-benzoxazole-5-carboxamide derivatives for antibacterial and antitubercular activities

A novel series of N-(4-oxo-2-substituted phenyl-1,3-thiazolidin-3-yl)-1,3-benzoxazole-5-carboxamide III (a-h) derivatives were synthesized by the reaction between Schiff bases of benzoxazole II (a-h) with thioglycollic acid. The purity of these compounds was confirmed by melting point and TLC. Structure of these compounds was confirmed on the bases of IR, 1H NMR, 13C NMR and Mass spectral data. All the synthesized compounds were screened for their antibacterial and antitubercular activity using broth microdilution method and Microplate Alamar Blue Assay (MABA) method respectively. For antibacterial and antitubercular activities screening ciprofloxacin, norfloxacin and isoniazid were used as standard drugs respectively. The results showed that compounds III c, III d and III f exhibited good antibacterial activity and compounds III c, III f, III g and III h showed good antitubercular activity.

Cu-Catalyzed Direct C-P Bond Formation through Dehydrogenative Cross-Coupling Reactions between Azoles and Dialkyl Phosphites

A direct dehydrogenative cross-coupling of azoles [C(sp2)-H] with dialkyl phosphites [P(O)-H] to access 2-phosphonated azoles using Cu(I)/Cu(II) as catalyst and K2S2O8/di-tert-butylperoxide as oxidant has been achieved. A remarkable advantage over reported procedures includes that oxazoles, imidazoles, benz(ox/othi/imid)azoles, and indole are found to react under optimized reaction conditions to provide corresponding adducts in high yields. The mechanistic insight of cross-coupling was obtained by deuterium kinetic isotope effect studies.

Synthesis, Structure Revision, and Cytotoxicity of Nocarbenzoxazole G

The total synthesis of nocarbenzoxazoles F (1) and G (2), originally obtained from the marine-derived halophilic bacterial strain Nocardiopsis lucentensis DSM 44048, was achieved via a simple and versatile route involving microwave-assisted construction of a benzoxazole skeleton, followed by carbon-carbon bond formation with the corresponding aryl bromides. Unfortunately, the 1H and 13C NMR spectra of natural nocarbenzoxazole G did not agree with those of the synthesized compound. In particular, the spectra of the isolated and synthesized compounds showed considerable differences in the signals from the protons and carbons in the aryl group. The revised structure was validated by the total synthesis of the actual nocarbenzoxazole G (8c) molecule, which is a regioisomer of the compound that was reported earlier as nocarbenzoxazole G. The synthesized derivatives showed specific cytotoxicity to the human cervical carcinoma cell line, HeLa, but did not have any remarkable effect on the other cell lines.
