The reaction of gamma-ketoaldehyde acetals with lithium trimethylsilyldiazomethane afforded 2-cyclopentenones via the 1,5-C-H insertion of alkylidene carbene in high to moderate yields. Using this method, the synthesis of trichodenone C was achieved. (C) 2000 Elsevier Science Ltd. All rights reserved.
