Engineering of indole-based tethered biheterocyclic alkaloid meridianin into β-carboline-derived tetracyclic polyheterocycles via amino functionalization/6-endo cationic π-cyclization

Agarwal, Piyush K.,Dathi, Meena D.,Saifuddin, Mohammad,Kundu, Bijoy

, p. 1901 - 1908 (2013/01/16)

A mild, efficient and versatile method has been developed for the construction of a functionalized natural product, meridianin, and its post conversion to pyrimido-β-carboline by cationic π-cyclization. The strategy involves the introduction of an amino g
