An atom-economic asymmetric [3 + 2] spiroannulation reaction of saccharine-derived cyclic 1-azadienes with α-hydroxy-1-indanones has been developed via bimetallic cooperative catalysis. The developed synthetic strategy achieved through Michael/O-Mannich cascade process...

An efficient kinetic resolution of racemic trans-2,3-aziridinyl alcohols is established via zinc catalyzed ring opening reactions with various amines as the nucleophiles. The directing effect of the hydroxyl group and the precise enantiodiscrimination by dinuclear zinc cooperative catalyst are the keys to success of high regioselectivity and enantioselectivity. A range of enantioenriched vicinal diamines and trans-2,3-aziridinyl alcohols were obtained in good yields with excellent ee values. To the best of our knowledge, this is the first example of directed enantioselective nucleophilic ring opening reactions of 2,3-aziridinyl alcohols.
