ChemInform Abstract: Hydrolysis of 2-Alkoxyalk-2-enals
Autor: T. N. Mamashvili, G. I. Sarapulova, Natalia A. Keiko, M. G. Voronkov
Publikováno v: ChemInform. 30
Hydrolysis of 2-alkoxyalk-2-enals with equimolar amount of water (in an organic solvent) and with an excess of water has been studied with the aim of synthesizing 2-oxopropanal (methylglyoxal). 2-Oxopropanal obtained in an excess of water exists in t

New Syntheses of the Bis-Guanylhydrazone and Bis-Thiosemicarbazone of Methylglyoxal
Autor: N. A. Keiko, T. N. Mamashvili
Publikováno v: Pharmaceutical Chemistry Journal. 39:82-83
New methods of synthesis of methylglyoxal bis-guanylhydrazone (as bis-hydrochloride) and methylglyoxal bis-thiosemicarbazone are developed, which are based on the reactions of 2-ethoxypropenal with aminoguanidine and thiosemicarbazide in an acid medi

Publikováno v: Bulletin of the Academy of Sciences of the USSR Division of Chemical Science. 36:1973-1975
The reaction of 2-methyl and 4(5)-methylimidazoles with acetylene in the presence of Gu2Cl2 leads to the corresponding N-vinyl derivatives. 1-Vinyl-4(5)-methylimidazole is formed as a mixture of two isomers differing in the position of the methyl gro
