The first example of a reagent-controlled enantioselective Pictet-Spengler reaction is demonstrated. Employing diisopinocampheylchloroborane as a chiral Lewis acid catalyst, the Pictet-Spengler reaction of Nb-hydroxytryptamine gave the corresponding 2-hydroxy-tetrahydro-β-carbolines up to 90 %ee.
证明了试剂控制的对映选择性Pictet-Spengler反应的第一个例子。使用二异硫代樟脑基氯硼烷作为手性路易斯酸催化剂,N b-羟基色胺的Pictet-Spengler反应得到相应的2-羟基-四氢-β-咔啉,最高可达90%ee。
