Heterogeneous Enantioselective Catalyzed Carbonyl‐ and Imino‐Ene Reactions using Copper Bis(Oxazoline) Zeolite Y

A recovery discovery: A simple pathway for the synthesis of α-hydroxy and α-amino carbonyl compounds with good yields and high enantioselection is provided by the first heterogeneously catalyzed enantioselective carbonyl-ene and imino-ene reactions. The catalyst is a bis(oxazoline)-modified CuH zeolite Y (Cu-HY)system (see scheme; Rox=CH3,H; Rbrg=Ph,C(CH3)3), which can easily be recovered and reused.
