Photocycloaddition of Quinoxaline-2(1H)-thiones to Alkenes

A synthetically useful C-C bond formation involving the photochemical addition of quinoxaline-2(1H)-thiones to alkenes is described.Irradiation of the quinoxaline-2(1H)-thiones 1-4 in the presence of the alkenes 7 gave the 2-(2'-mercaptoalkyl)quinoxalines 8-11 in moderate-to-good yields via ring cleavage of an intermediate aminothietane with aromatization of the quinoxaline ring.The latter was formed by photocycloaddition of the C=S bond of the quinoxaline-2(1H)-thione and the C=C bond of the alkene.

In contrast with their oxo-analoques (1), quinoxalin-2-thiones (3) undergo photo-induced addition to cyclohexene (4a), methacrylonitrile (4b), and methyl methacrylate (4c) to give 2-substituted quinoxalines (6-14)
