Herein we report the first asymmetric Michael reaction of arylidene‐isoxazol‐5‐one with 1,3‐diesters. Despite complex tautomer equilibria of the obtained Michael adducts, the one‐pot entrapping strategy by the aid of different electrophiles/protecting groups led to the selective isolation of diverse N‐substituted isoxazol‐5‐ones in very high overall yield and good enantioselectivity. Asymmetric three...
