We prepared a series of substituted aminocyanopyrroles and another of aminocynaothiophenes. We describe an efficient new one-step synthetic strategy via the condensation of an alkyl sarcosinate and ethoxymethylenemalononitrile, through a Gewald-like

The crystallization of (C 11 N 4 H 10 ) 2 ·H 2 O (I) and (C 11 N 4 H 10 ) 4 ·H 2 O (II) is made by slow evaporation from aqueous solutions. The structures of these compounds have been solved and refined by single-crystal X-ray diffraction data. The

Several new pyrazolopyrimidine compounds were achieved from aminocyanopyarazole 1. The starting material 1 was initially coupled with orthoester at refluxed with various primary amines, ammonia, hydrazines and hydroxylamine to furnish a series of pyr

A three-component condensation reaction between aminopyrazolo[3,4- d ]pyrimidine, an aldehyde, and an isocyanide catalyzed by scandium triflate yields a series of heterocyclic derivatives of imidazo[1,2- c ]pyrazolo[3,4- d ]pyrimidine in good yields,

Acidic hydrolysis of Ugi adducts formed from α-hydrazonocarboxylic acids and aminoacetaldehyde dimethyl acetal leads to the fragmentation of aminoacetaldehyde residues with final formation of pyrazoles. An aldol-type reaction of the hydrazone is pro
