Abstract:The synthesis of cyclobutane derivatives including 1,1-dibromo-3-phenylcyclobutane, 1,1-dibromo-3-ethylcyclobutane and 1,1-dibromo-3-ethylcyclobutane was studied in this paper. The synthesis routes involves such reactions as alkylation of diethyl malonate, reduction of ester, sulfonylation of alcohol, cyclization of sulfonylate and diethyl malonate, hydrolysis of ester and substitution of carboxyl group with bromine. The results show that the suggested synthesis method is simple, convenient and feasible to ...
