trans-C-Glycosides from 8-oxabicyclo[3.2.1]oct-6-en-3-one — Synthesis of the C3–C13 segment of the phorboxazoles A and B
摘要:
The enantiopure and fully resolved C3-C13 segment of the phorboxazoles A and B has been prepared in 14 steps in 24% overall yield starting from 8-oxabicyclo[3.2.1]oct-6-en-3-one. Key steps are the desymmetrization of the oxabicyclic ketone, the anomeric allylation and the asymmetric allylboration. (C) 1999 Published by Elsevier Science Ltd. All rights reserved.

A variety of analogues of phorboxazole C15-C26 segment have been prepared via three different reaction sequences. Structure activity investigations of the oxazole substitution pattern point to a pharmacophoric lead structure.
