摘要：

Polyaromatic organic compounds have attracted significantattention because of their wide range of applications in various func-tional materials. Recently, transition-metal-catalyzed C-H bond activa-tion and the subsequent oxidative cyclization with unsaturated com-pounds has emerged as a promising synthetic method for multiringsystems. We report a two-step synthesis of binaphthyl-fused chiralbibenzo[g]coumarin derivatives by Rh-catalyzed annulative coupling re-action of BINOL-based thiocarbamates with alkynes. The optical prop-erties of the coupling products were evaluated
