Diversity Oriented Routes to Thiopeptide Antibiotics: A Solution to the “Thiazole Problem”

Abstract

The Goossen decarboxylative coupling reaction enables the union of thiazole-2-carboxylic acids with a 2-pyridyl triflate, leading to the formation of pyridine-thiazole clusters of the kind found in thiopeptide antibiotics. The method avoids problematic or technically challenging reaction sequences involving 2-thiazolyl organometallics, facilitating the investigation of the structure–activity relationship of the thiopeptides.
