The formation of chiral γ‐butenolides has been achieved with good yields (up to 90%), high enantioselectivity (up to 91%) and diastereoselectivity (up to 9/1, anti‐selective) through an organocatalyzed vinylogous Mukaiyama aldol reaction of 2‐(trimethylsilyloxy)furan and aldehydes. A wide range of chiral γ‐butenolides was obtained under mild conditions by this methodology.
