摘要
The 9,10-dicyanoanthracene-sensitized photooxygenation of l-alkyl-2,3-diarylcyclopropanes in CH3CN afforded c-4-alkyl-r-3,t-5-diaryl-l,2-dioxolanes in excellent yields with high stereoselectivity, which upon hydrogenolysis on Pd-charcoal gave quantitatively the corresponding l,2-threo-2,3-erytftro-2-alkyl-l,3-diaryl-l,3-diols. The mechanistic feature of this photoreaction is described. © 1990, American Chemical Society. All rights reserved.
