Arylhexahydroisoquinolines Made Simple

Author: Saskia Neubacher

Using conventional synthetic pathways, arylhexahydroquinolines are difficult to prepare. Young Keun Chung and co-workers, Seoul National University, Korea, have developed a synthetic strategy from azabicyclo[4.1.0]heptene derivatives using Rh(PPh3)2(CO)Cl/AgBF4 in 1,2-dichloroethane. The bicyclo[4.1.0]heptene derivatives are easily accessible from the corresponding cyclopropylenynes via PtCl2-catalyzed cycloisomerization. By screening different derivatives of bicyclo[4.1.0]heptenes, it became apparent that an aryl group was needed in the 1-position and a cyclopropyl group in the 6-position for efficient rearrangement to take place.

A plausible reaction mechanism is proposed.
