Description

(S)-SIPHOS is a chiral auxiliary designed for asymmetric synthesis, featuring a sterically defined scaffold that enables high enantioselectivity in C–C bond formation. This bench-stable, moisture-tolerant reagent integrates seamlessly into synthetic workflows requiring precise stereocontrol.

Application

(S)-SIPHOS serves as a highly effective chiral ligand in palladium-catalyzed cross-coupling reactions, enabling enantioselective C–C bond formation under mild conditions. Its robust bench stability and excellent functional group tolerance facilitate reliable synthesis of complex chiral intermediates. Widely employed in medicinal chemistry and process development, it functions as a versatile tool for constructing stereodefined architectures in API-relevant scaffolds.
