Abstract

AbstractA simple and efficient method for the synthesis of tricyclic imidazolines derivatives via [3 + 2] 1,3‐dipolar cycloaddition between nonstabilized azomethine ylide generated in situ with unactivated cyclic imines is reported here. The method provided easy and mild access to various fused tricyclic hexahydroimidazo[5,1‐a]isoquinolines in excellent yields (up to 96%). This protocol is simple and easy to handle.
