THE CONDENSATION OF α-SUBSTITUTED ACETOACETATES WITH PHENOLS. PART III. THE PECHMANN CONDENSATION OF ETHYL α-(α-HYDROXY-βββ-TRICHLOROETHYL)-ACETOACETATE
The Pechtnann condensation of phenols with ethyl α-(α-hydroxy-βββ-trichloroethyl)- acetoacetate has been studied with a view to finding the effect of -CH(OH)CCl3 group as an α-substituent on the course of the reaction. Various coumarins containing -CH(OH)CCl3 in 3-position and their derivatives have been synthesised.doi:10.5281/zenodo.6610296 fatcat:sutnxbfvw5hexhufj5wmx37zwq
