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.
通过2的有机乙烯基乙烯基Mukaiyama醇醛醇醛缩醛反应2可以形成高收率(高达90%),高对映选择性(高达91%)和非对映选择性(高达9/1,抗选择性)的手性γ-丁烯内酯。 -(三甲基甲硅烷氧基)呋喃和醛。通过这种方法,在温和的条件下获得了广泛的手性γ-丁烯内酯。
