A versatile, readily accessible triad of 2-enoxy silane synthons derived from furan, pyrrole, and thiophene is presented. These heterocycles, in reacting with carbonyl and carbonyl- related acceptors, act as vinylogous nucleophile modules, giving rise to diverse, functionality- rich, γ-substituted α,β-unsaturated carbonyl constructs. These, in turn, are invaluable platforms onto which further functional elements and chirality may be introduced. A couple of appealing applications—the variable construction of a repertoire of carbasugars and a library of annonaceous acetogenin segments—have been chosen to illustrate the viability of this vinylogous aldol approach.

Abstract

A versatile, readily accessible triad of 2-enoxy silane synthons derived from furan, pyrrole, and thiophene is presented. These heterocycles, in reacting with carbonyl and carbonyl- related acceptors, act as vinylogous nucleophile modules, giving rise to diverse, functionality- rich, γ-substituted α,β-unsaturated carbonyl constructs. These, in turn, are invaluable platforms onto which further functional elements and chirality may be introduced. A couple of appealing applications—the variable construction of a repertoire of carbasugars and a library of annonaceous acetogenin segments—have been chosen to illustrate the viability of this vinylogous aldol approach.
