Crystallization-induced dynamic resolution
WebMay 25, 2024 · Notably, deracemization of α-tertiary carbonyl compounds has also been accomplished by leveraging host − guest chemistry [48], [49], [50] or crystallization-induced dynamic resolution [14], although stoichiometric amounts of chiral reagents were required in these cases. WebHerein we present a new example of coordination-mediated resolution of racemic acids by a chiral acid. The reaction of copper(II) acetate monohydrate, optically pure O,O′-dibenzoyltartaric acid (DBTA) and racemic α-bromo-2-chlorophenylacetic acid (HL 1) in acetonitrile solution afforded a binuclear copper(II) complex with D-DBTA dianion, α …
