Stereo- and regio-specific photochemical cycloaddition of furan to benzonitrile and phenylacetylene
Abstract
Benzonitrile and phenylacetylene undergo exclusive regio- and stereo-specific 2,6-, 2′,5′-photocycloaddition of furan: excited state interaction between the substituent and furan is considered to orient the addends and direct the reaction of this specific mode of attack.
