Applications of Organosilanes in Visible Light-induced Catalytic Asymmetric Reactions

Over the past decades, visible light-mediated photocatalysis has found a mainstream of applications in synthetic chemistry. Organosilanes have been proven to be a useful class of electron donors to generate the highly active radical species via photoinduced single electron transfer oxidation/fragmentation sequence, which may undergo follow-up radical coupling or addition process. This minireview highlights the comprehensive advances of organosilanes in photoredox catalyzed asymmetric organic synthesis, with particular emphasis placed on reaction mechanisms. We hope that this review will inspire further design and development of new reactions with such class of readily accessible reagents. This review provides the overview of comprehensive advances in the chemistry of organosilanes in asymmetric photoredox catalyzed organic synthesis, which are introduced from the mechanism perspective including C-Si bond cleavage and C-H bond cleavage of organosilanes. It is hopeful to provide guidance and assistance for the development of this field in future. image
