Abstract

the partial hydrolysis of X and VII, respectively, during the workup of the reaction mixture. Inasmuch as three moles of base are necessary to produce the orthoester X from the ketene acetal VI1 and chloroform, it would be expected that unreacted VI1 would remain when only the one mole of base required to form the cyclopropanone acetal VI11 was used. The formation of X from VI11 means that this acetal effectively competes with the chloroform for ...
