(Chemical Equation Presented) 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.
