The synthesis of thiathromboxane analogues
Abstract
Thiathromboxane analogues (2) and (19) have been prepared by an extremely short and efficient synthetic route which can also be employed to make simple 2,3-dialkylated thian-4-ones. The cornerstone of the synthetic strategy is the organocopper conjugate addition – enolate alkylation reactions of 3-methoxycarbonyl-5,6-dihydrothiin-4-one (1b).
