The reaction may proceed in a concerted asynchronous manner. Although we did not observe single addition products, we cannot exclude a stepwise mechanism of cycloaddition formation. The stereochemistry of the adducts can be rationalized based on an anti-oriented nitrone ylide/enolate, and s-cis conformation of the endo-placed acrylate ester. The stereochemical outcome of the cycloadducts 13 and 14 was assigned by analogy to 11
