产品说明

一般描述

Dimethyl chloromalonate (dimethyl 2-chloromalonate) is a dialkyl 2-substituted malonate. Carbanions of dimethyl chloromalonate are reported to react with naphthoquinone derivatives, via vicarious nucleophilic substitution or oxidative nucleophilic substitution of hydrogen processes. Dimethyl chloromalonate is reported to react with hydroquinone and monosubstituted hydroquinones to afford 2-oxido-benzo[b]furan derivatives. Synthesis of dimethyl 2-chloromalonate, via chlorination of dimethyl malonate has been reported.

应用

Dimethyl chloromalonate is suitable for use in the synthesis of 4,5,6-trichloropyrimidine. It may be used in the stereoselective synthesis of highly functionalized nitrocyclopropanes. It may be used in one-pot synthesis of tetra-alkoxycarbonylallylidenetriphenylphosphoranes.
