摘要
In this paper, we report a novel approach to the heteroaryl-condensed nuclei of natural furo[3,2- a]carbazole alkaloids. Our synthetic studies use N-phthaloyl tryptophan methyl ester as starting material and zinc ion mediated transamination reaction as the key step. This work also implicated a novel strategy to assemble other [a]-fused carbazoles.
