Alkylation of CH Acids with Haloidalkyl-1,3-dioxolanes

摘要

Alkylation of diethyl malonate and Meldrum acid with haloalkyl-1,3-dioxolanes has afforded the substituted malonates; their decarboxylation has led to the formation of esters containing a cycloacetal fragment. Reactions of the substituted malonates with urea have yielded the corresponding substituted barbiturates. Monodecarboxylation of the obtained malonates has led to the formation of 1,3-dioxolane-carboxylates.
