A straightforward enantiomerically pure synthesis of the heterocyclic core of the D-series GE2270 is reported. The synthetic strategy combines the Hantzsch thiazole's building condensation with a cross-coupling reaction including direct C-H hetarylation to build and connect step-by-step thiazolyl moieties to the 5-bromopicolinate as readily available starting material.

Phenylalanine inhibited thiazole biosynthesis in a thiamine-regulatory mutant of Escherichia coli, and the inhibition was overcome by tyrosine.

PURPOSE This article makes an attempt to synthesize certain compounds containing thiazole and imidazole moieties and screen for the antimicrobial properties. METHODS The novel compounds synthesized were characterized by elemental analysis, IR and (1)HNMR spectral data. The antimicrobial activity of novel compounds was evaluated by cup plate method. RESULTS The compound p-t showed more antib...

Different approaches have been studied in order to prepare efficiently the sulfur rich electron acceptor, DEBTTT. Among the various routes used, the one going through the synthesis of a bicyclic derivative, where the thiazole-2-chalcogenone is fused with a 1,3-dithiole-2-one, leads to the target molecule under milder conditions and better yield. Thus, this approach has been explored for the syn...
