Abstract
The total synthesis of (-)-epothilone A by a convergent route is reported. The synthesis of the required key intermediates has been improved with respect to stereoselectivity and availability. The access to ethyl ketone 2 has been significantly improved by employment of chiral acetate equivalents, which provided higher optical and chemical yields. Key intermediate 3 was obtained by oxazolidinone auxiliary techniques and stereoselectively coupled with 2 by an aldol reaction. After esterification with thiazole fragment 4, (-)-epothilone A was finally constructed by using ring-closing metathesis.
