Two birds with one stone: Magnesium‐base‐catalyzed highly diastereoselective direct‐type aldol reaction of glycine Schiff base bearing a fluorenylidene moiety as a protecting and activating group was developed. The desired reactions proceeded smoothly at low temperature, and the aldol products were obtained in high yield with high diastereoselectivity.
