Enzymatic resolution of thiazole-containing vinyl carbinols. Synthesis of the C12–C21 fragment of the epothilones
摘要:
An operationally simple enzymatic kinetic resolution has been applied in an efficient synthesis of C12-C21 fragment of epothilones. The key step, a lipase resolution, has been employed on three different thiazole-containing vinyl carbinol substrates to give highly enantiomerically enriched alcohols bearing the key C15 stereocenter.
