Abstract

Condensation of the dianions derived from E-3-(phenylthio)-prop-2-enoic acid and its 2-methyl homologue with aldehydes and ketones provides a facile one step synthesis of 5-substituted 4-phenylthio-2(5H)-furanone derivatives. The application to the synthesis of sesquirose furan and bullatenone is described.
