Versatile and expeditious synthesis of aurones via Au I-catalyzed cyclization.

Hassina Harkat1, Aurélien Blanc, Jean-Marc Weibel, Patrick Pale.   

Abstract

Aurones are conveniently formed in a three-step procedure including a goldI-catalyzed cyclization of 2-(1-hydroxyprop-2-ynyl)phenols as a highly regio- and stereoselective key step. A wide diversity of derivatives can be obtained starting from substituted salicylaldehydes. Synthesis of natural 4,6,3',4'-tetramethoxyaurone and structure revision of two natural products (dalmaisione D and 4'-chloroaurone) were achieved.
