Theoretical Insights into Ester-Directed Reactions between Propiolates with 1,2-Benzisoxazoles by Au(I) Catalyst: [4 + 2]-Annulation versus Michael-Type Products

Au(I)-catalyzed selective reactions of Et- and tBu-substituted propiolates (1a and 1a′) with 1,2-benzisoxazole(2a) provide a new strategy for purposefully access to desired bioactive heterocycles. ...
