摘要：
An organocatalytic enantioselective Strecker reaction for the synthesis of 3-amino-3-cyanooxindoles has been developed. Employing a quinine-derived thiourea catalyst, the nucleophilic addition of trimethylsilyl cyanide to N-Boc-ketimines affords 3-amino-3-canooxindoles in good to excellent yields (7898%) and very good enantioselectivities (up to 94%). Furthermore, to the best of our knowledge, this method also represents the first enantioselective organocatalyzed Strecker reaction with N-Boc-ketimines as electrophiles.
