Two naturally occurring β-carbolines, 6-methoxy-2-methyl-1,2,3,4-tetrahydro-β-carboline and bauerine A, have been prepared using a Stille-type coupling, followed by a palladium-phosphine catalyzed N-heteroannulation as the key steps.
两种天然存在的β-咔啉,6-甲氧基-2-甲基-1,2,3,4-四氢-β-咔啉和bauerine A,均采用Stille型偶联方法制备,然后使用钯膦催化的N -异质环化是关键步骤。
