from cyclopentene‐1,3‐diones, with 2‐mercaptobenzothiazoles has been realized. It was efficiently catalyzed by a chiral DyIII/N,N′‐dioxide complex through a thiolysis/elimination sequence. This remote stereocontrol strategy provides facile access to synthetically versatile cyclopentene derivatives bearing an all‐carbon quaternary stereogenic center in high yield and excellent enantioselectivity.
