Two-photon route to N-vinylisoindolinones from isoquinolin-1(2H)-one and electron deficient ethenes
Abstract
Isoquinolin-1(2H)-one undergoes regiospecific and highly stereoselective (2π+ 2π) photocycloaddition with electron deficient ethenes at wavelengths longer than 290 nm: with 254 nm radiation, the adducts rearrange to N-vinylisoindolinones and undergo retroaddition.
