The textbook photoreaction between two alkenes is the [2 + 2]-photocycloaddition resulting in functionalized cyclobutanes. Herein, we disclose an unusual reactivity of alkenes that favor photoene reaction over the [2 + 2]-photocycloaddition.

New axially chiral N-acryl-N-allyl-o-tert-butylanilide and N-(o-tert-butylphenyl)-2-methylmaleimide with high optical purity and definite absolute configurations were prepared from o-tert-butylaniline and (S)-O-acetyl lactic acid or (R)-2-methylsuccinic acid, respectively. Iodine- or Lewis acid-mediated asymmetric Diels-Alder reaction of these axially chiral compounds with various dienes proceeded with high endo and diastereofacial selectivity.
