Abstract

The synthetic versatility of a special collection of heterocyclic dienoxy silane synthons based on furan, pyrrole, and thiophene to access valuable building blocks to be used in the fabrication of complex molecular architectures is featured. Accessed by base-assisted enolsilylation of alpha,beta-unsaturated lactone or lactam precursors, silyloxydiene heterocycles easily couple in a strictly vinylogous sense to diverse electrophiles, such as aldol-, Mannich-, and Michael-type acceptors, to generate butenolide-type intermediates for viable use in asymmetric synthesis. A survey of our own achievements in this realm, along with preeminent contributions by other research groups reveal the unique merits of silyloxy diene chemistry and highlight these reactions as a key gateway to an array of multifunctional natural or natural-like constructs.
