REGIOSELECTIVITY OF PHOTOINDUCED INTRAMOLECULAR ARENE-OLEEIN META-CYCLOADDITION
摘要:
The photoinduced intramolecular arene-olefin meta-cycloaddition of 1 gave regio-selectixely products 2a and 2b,whereas under the same conditions, 3a and 3b provided 4a and 4b respectively.The structure of the photo products was established by detailed 2D-NMR methodology.The observed regioselectivity was rationalized in terms of the stabilization of the zwitterionic intermediates by alkyl group at the phenyl ring.
