Abstract

Abstract : This work reports a catalytic method that affords seven-membered carbon rings via expansion of β-ketoesters. This method tolerates alkynyl 1, 2-diketones, common ynones, and alkynyl ketoesters, and affords the products with multiple functional groups. Abstract : A catalytic method affording seven-membered carbon rings via two-carbon expansion of five-membered β-ketoesters has been developed. This method tolerates various alkynyl 1, 2-diketones, common ynones, and alkynyl ketoesters, and affords the corresponding products with multiple functional groups under mild and environmentally benign conditions.
