Abstract
The enantioselective aldol reaction has drawn considerable attention for its atom
economy. Numerous metal-catalyzed and organocatalytic asymmetric aldol methods for
dienolsilanes (1,3-dienyloxysilane-based systems) have been developed during the past
decade. The main aim of this review is to present recent developments in asymmetric
aldol reactions with aldehyde-, ketone-, and amide-derived dienolsilanes, and heterocyclic
α,β-unsaturated ester derived dienolsilanes, which have found considerable application
in the synthesis of natural products and bioactive chemicals.
