Abstract

CO2CHa CH. 2 CHI XIV quivocal synthesis of XIV from phenylmagnesium bromide and I established their non-identity. In an effort to improve the yield of (11), the Friedel-Crafts reaction was carried out in the presence of antimony pentachloride. 12 With this catalyst none of the ketoacid I1 was formed, but instead the keto lactone X was isolated in 44% yield. This lactone could be condensed further with benzene and aluminum chloride to give the ...
