2-Chloroquinoline-3-carbaldehyde 1 reacts with 2-cyanoacetohydrazide in ethanol to result in 1-[1-aza-2-(2-chloro(3quinolyl))vinyl]-2-cyanoacetamide 2. Phenyl isothiocyanate added to a stirred solution of compound 2, sulphur and triethylamine in a mixed solvent of dimethylformamide : ethanol to result in N-[1-aza-2-(2-chloro(3-quinolyl))vinyl](4amino-3-phenyl-2-thioxo(1,3-thiazoline-5-yl)) carb...
Hydrazonyl bromides 2a,b reacted with active methylene compounds (dibenzoylmethane, acetylacetone, ethyl acetoacetate, phenacyl cyanide, acetoacetanilide, ethyl cyanoacetate, cyanoacetamide and malononitrile) to afford the corresponding 1,3,4,5- tetrasubstituted pyrazole derivatives 5-12a,b. Reaction of 12a,b with formamide, formic acid and triethyl orthoformate give the pyrazolo[3,4-d]pyrimidi...
A bacterial strain able to use cyanide as the sole nitrogen source under alkaline conditions has been isolated. The bacterium was classified as Pseudomonas pseudoalcaligenes by comparison of its 16S RNA gene sequence to those of existing strains and deposited in the Coleccion Espanola de Cultivos Tipo (Spanish Type Culture Collection) as strain CECT5344. Cyanide consumption is an assimilative p...
