Solvent-Triggered Breakdown of Solid Solution Behaviour Enables Direct Enantioselective Crystallization of RS-Phenprocoumon

Abstract

We show that solvent selection plays a decisive role in chiral resolution of RS-phenprocoumon-quinidine. In particular, formation of a bis-acetone solvate suppresses solid solution formation, and affords spontaneous enantioselective crystallization of S-phenprocoumon with enantiomeric excesses of up to 92% in a single resolution step.
