Novel Gold(III) Polymer-Supported Catalyst for Indole Library Synthesis

摘要

Immobilized catalysts provide among the most effective tools for chemical library synthesis because the procedures are simple and applications to automated systems are feasible.In recent years,use of gold catalysts in organic synthesis has expanded rapidly,and accordingly,development of immobilized gold catalysts is strongly demanded.In the course of our program to develop new methods for library synthesis,we focused on indole ring formation with a gold(III) catalyst reported by Marinelli et al.(Scheme l).
