Hetero-Diels–Alder synthesis of the spiroketal fragment of reveromycin A
摘要:
The asymmetric synthesis of the 6,6-spiroketal fragment 15 of the epidermal growth factor inhibitor reveromycin A (1) is described. A hetero-Diels-Alder reaction was utilized to construct the 6,6-spiroketal 14 and subsequent stereoselective hydroboration provided reveromycin A spiroketal 15. (C) 2000 All rights reserved.

Reveromycin A (1) belongs to a family of microbial polyketides with unusual structural features and biological activities. The structure of 1 is composed of a [6,6] spiroketal core decorated with highly unsaturated side chains, As a prelude to the synthesis of 1, we present herein a short, efficient, and enantioselective synthesis of the C9-C21 fragment 5 (spiroketal core) of reveromycin A.
