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...

The title compound, C(21)H(22)N(4)O(2)S(2)·0.5H(2)O, crystallizes with two mol-ecules in the asymmetric unit. The dihedral angles between the phenyl and imidazothiazole ring systems are 19.16 (9) and 21.37 (9)°. In the imidazothiazole ring systems, the cyclohexane rings adopt chair conformations, while the thiazole rings have distorted envelope conformations. The two mol-ecules are stabilized b...

The synthetic utility of 3,3'-(3,4-dimethylthieno[2,3-b]thiophene-2,5-diyl)bis (3-oxopropanenitrile) (1) in the synthesis of some novel bis-[1,3,4-thiadiazole] 6a-g and bis-thiazole 10 and 13 derivatives with thieno[2,3-b]thiophene moiety is reported. Antimicrobial evaluation of some selected examples from the synthesized products was carried out and showed promising results.

The title compound, C24H18N4S3, exhibits three near planar benzo-thia-zole systems in a pseudo-C 3 conformation. The dihedral angles between the planes of the benzo-thia-zole groups range from 112.56 (4) to 124.68 (4)° In the crystal, mol-ecules are connected to each other through three short C-H⋯N contacts, forming an infinite chain along [100]. The molecules are also linked by π-π interaction...
