The Uses of Ethyl malonyl chloride
Employed in the synthesis of 3-pyrrolin-2-ones via amidation with propargylamines and subsequent base catalyzed 5-exo-dig cyclization.1
The Uses of Ethyl malonyl chloride
Ethyl malonyl chloride is used in the syntheses of methanofullerodendimers and 3-pyrrolin-2-ones. It plays a vital role in the preparation of 3,5-disubstituted 1,2,4-oxadiazole derivatives, which are potential peptidomimetic building blocks. It is a versatile acylating agent for propargyl alcohols, hydrazines and amines.
General Description
