研究了酮亚胺与氰化钾的催化不对称Strecker反应。对照实验表明,该反应不可避免地降低了产物收率和对映体选择性。使用质子添加剂与手性1,2,3 -三唑离子结合作为催化剂,可以对各种酮亚胺进行高效和对映选择性的氰化物加成。
A catalytic asymmetric Strecker reaction of ketoimines with potassium cyanide (KCN) is developed. Control experiments reveal the involvement of a retro‐Strecker reaction, which inevitably decreases the product yield and enantioselectivity. The use of a protic additive in combination with a chiral 1,2,3‐triazolium ion as a catalyst allows for the highly efficient and enantioselective cyanide addition to various ketoimines.
