Abstract
Transition-metal-catalyzed asymmetric allylic substitution reactions represent a hot
research topic in the field of asymmetric synthesis, with significant progress having
been made. Among diverse catalysis systems, relay catalysis enables sequential activation
of multiple steps in one pot and the rapid construction of multiple chiral centers,
providing a simple and powerful platform for organic synthesis. Recently, relay catalysis
has been successfully applied to asymmetric allylic substitution reactions, and a
variety of challenging transformations have been realized. This Short Review summarizes
the related progress on asymmetric allylic substitution reactions based on relay catalysis
over the last decade.
