PHOTOCYCLOADDITION OF 6-CYANOPHENANTHRIDINE TO ELECTRON-RICH OLEFINS
Irradiations of 6-cyanophenanthridine in the presence of electron-rich olefins afforded the corresponding azocine and azetidine derivatives regiospecifically via their exciplex intermediates.
The Photocycloaddition of 6-Substituted Phenanthridines to Electron-rich Olefins
The photocycloaddition reaction of 6-substituted phenanthridines and electron-rich olefins, such as trans-anethole and phenyl vinyl ether, is described.This reaction proceeds from the 1(?,?*) states of 6-substituted phenanthridines via the exciplex to give azocine and/or azetidine derivatives in ethanol.
