A one-pot condensation of isotryptamines and aldehydes that affords enantiomerically enriched 4-substituted tetrahydro-γ-carbolines is reported. The reaction is induced by a chiral thiourea/benzoic acid dual catalyst system. Purification of the N-Boc-protected products by trituration or crystallization provides the optically pure tetrahydro-γ-carboline derivatives in a scalable and highly practical
据报道,异色胺和醛的一锅缩合可提供对映体富集的 4-取代四氢-γ-咔啉。该反应由手性硫脲/苯甲酸双催化剂体系引发。通过研磨或结晶纯化N -Boc 保护的产物,以可扩展且高度实用的程序提供光学纯的四氢-γ-咔啉衍生物。
