Overview

Ethyl malonyl chloride is a versatile acylating agent for propargyl alcohols, hydrazines and amines.

Ethyl malonyl chloride was used in the synthesis of:

. liquid-crystalline methanofullerodendrimers;

. 3,5-disubstituted 1,2,4-oxadiazole derivatives, which are potential peptidomimetic building blocks;

. 3-pyrrolin-2-ones via amidation with propargylamines and subsequent base catalyzed 5-exo-dig cyclization
