Abstract

A facile and convenient synthetic method for the anticancer agent elesclomol and its analogues, N1,N3-dialkyl-N1,N3-bis(arylcarbonothioyl)malonohydrazides, by the direct coupling of N-alkyl-N-(substituted)benzothiohydrazides and substituted malonic acids using propylphosphonic anhydride (T3P®) under very mild conditions has been developed.
