Abstract

A Rh(iii) catalyzed formal [4 + 2 + 2] cyclization of -pivaloyloxybenzamides with 1,6-allene-enes by C-H functionalization is reported. The reactions occur at room temperature and are compatible with air and moisture with a tolerance of many synthetically useful functional groups. The follow-up modifications of the products have been demonstrated. After careful mechanistic studies and DFT calculation, a reaction mechanism was proposed.
