Role of gold in a complex cascade reaction involving two electrocyclization steps.

Jason G Harrison1, Dean J Tantillo.   

Abstract

Quantum chemical computations (B3LYP/LACVP**) were applied to assess the impact of Au(I) complexation on activation barriers for sequential electrocyclization reactions (one a 1,2-dihydroazete ring-opening and another a pentadienyl cation ring-closure) proposed to occur during a complex reaction cascade that converts alkynes and imines to cyclopentenimines.
