Abstract:Hydrofunctionalization of alkynes is one of the most efficient ways to access axially chiral styrenes with open‐chained olefins. While great advances have been achieved for 1‐alkynylnaphthalen‐2‐ols and analogues, atroposelective hydrofunctionalization of unactivated internal alkynes lags. Herein we reported a platinum‐catalyzed atroposelective hydrosilylation of unactivated internal alkynes for the first time. With monodentate TADDOL‐derived phosphonite L1 used as a chiral ligand, various axially chiral styre… Show more
