General description

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

Application

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
Versatile acylating agent for propargyl alcohols, hydrazines, and amines.
