Resumo

A new route was developed to design esters of gem-dicarboxylic acids of cyclopentene series by CH alkylation of diethyl malonate with cis-1,4-dichlorobutene. Diethyl cyclopent-3-ene-1,1-dicarboxylate was reacted with dichlorocarbene. The structures of the isolated compounds were described in detail by ¹H, ¹³C NMR spectroscopy and GC–MS.
