Three-component bis-heterocycliation for synthesis of 2-aminobenzo[4,5]thieno[3,2-d]thiazoles

Organic Chemistry Frontiers, 2019
A cooperative base system has been developed for the novel three-component synthesis of 2-aminobenzo[4,5]thieno[3,2-d]thiazoles via bis-heterocyclization of methylketoxime acetates.

Synthesis of Oligonucleotides Containing Thiazole and Thiazole N-Oxide Nucleobases

Organic Letters, 2002
[reaction: see text] The thiazole C-nucleoside analogue was synthesized by the Hantzsch cyclization method to form the thiazole ring and was then converted to the thiazole N-oxide C-nucleoside analogue by peracid oxidation of the heterocycle nitrogen.

The Thiazole Aldehyde Synthesis

Synthesis, 1998
Aldehydes with diverse structural arrays are prepared by construction of carbon chains at C-2 of the thiazole ring and conversion of the heterocycle into the formyl group. Various methods are described that differ depending on the type of thiazole-based reagent employed in the initial carbon-carbon bond forming reaction leading to 2-substituted ...
