enantioselective catalysts for the asymmetric Pictet–Spengler reaction of Nb‐α‐naphthylmethyl tryptamines with a series of aliphatic and aromatic aldehydes, affording opticallyactive tetrahydro‐β‐carbolines in excellent yields and ee values. The current protocol has been applied in the asymmetric total synthesis of (−)‐harmicine.
手性SPINOL-磷酸是N b -α-萘甲基甲基色胺与一系列脂族和芳族醛的不对称Pictet-Spengler反应的高度对映选择性催化剂,可提供具有优异收率和ee值的旋光四氢-β-咔啉。当前协议已应用于(-)-甜菜碱的不对称总合成中。
