摘要

Aryl substituted benzoylacrylic acids are readily prepared from maleic anhydride,'and dibenzoylethylenes from fumaryl chloride, 2 by the Friedel and Crafts reaction. The products thus obtained are yellow in color, are the stable forms as regards stereochemical rearrangements and undoubtedly possess the trans~ onfiguration.”~'~ The cis forms of many unsaturated 1, 4-diketones are prepared by the action of sunlight on the trans isomers, 2J ...
