A novel tandem Mannich/intramolecular aminal formation between tryptamines and salicylaldehydes was reported. This strategy provides a promising approach for the stereoselective synthesis of a range of complex fused spiroindolines, which bear a highly congested contiguous spiro quaternary center and two tertiary stereocenters, in a highly economical and effective fashion.
据报道,在色胺和水杨醛之间形成了一种新型的串联曼尼希/分子内氨基形成。该策略为以高度经济和有效的方式立体选择性合成一系列复杂的稠合螺二氢胆碱提供了一种有前途的方法,螺二氢胆碱具有高度拥挤的连续螺四价中心和两个叔立体中心。
