Reduction of alkyl-2-amino-5,6-dialkyl-3-cyanopyridine-4-carboxylates with sodium borohydride in protic solvents gave rise to 4-amino-3-imino-6,7-dialkyl-1,3-dihydrofuro[3,4-c]pyridines that at hydrolysis in acid medium afforded the corresponding lactones.__________Translated from Zhurnal Organicheskoi Khimii, Vol. 41, No. 2, 2005, pp. 288–291.Original Russian Text Copyright © 2005 by Vasil’ev, Lyshchikov, Nasakin, Kayukov, Tafeenko. 相似文献

An unusual direction has been found for the interaction of alkyl 5,6-dialkyl-2-amino-3-cyanopyridine-4-carboxylates with primary amines leading to the formation of 2,6,7-trialkyl-4-amino-2,3-dihydro-1H-pyrrolo[3,4-c]pyridine-1,3-diones. 相似文献

2-Aryl-1,2,3,4-tetrahydropyridine-3,3,4,4,-tetracarbonitriles and 1,3,5-triaryl-9-oxo-1,2,3,4b,5,6,8a,9-octahydropyrido[3,4:3,4]pyrrolo[1,2-a][1,3,5]triazine-4b,8a-dicarbonitriles are formed by the reaction of 4-oxoalkane-1,1,2,2-tetracarnonitriles with 1,3,5-triaryl-2,4-diaza-1,4-pentadienes depending on the solvent used.Chuvash State University, Cheboksary 428015.

It has been established by x-ray structural analysis that on reacting 4-oxoalkane-1,1,2,2-tetracarbonitriles with aldehydes
6-imino-2,7-dioxabicyclo[3.2.1]octane-4,4,5-tricarbonitriles are formed and not 3-imino-2,6-dioxabicyclo[2,2,2] octane-4,8,8-tricarbonitriles
as has been proposed.

3-Benzoylcyclopropane-1,1,2,2-tetracarbonitrile reacted with water to give 2-benzoyl-1,3-dicyanocyclopropane-1-carboxamide
as a result of hydrolysis of the cyano group in the trans position with respect to the carbonyl group and subsequent decarboxylation. The reaction of 3-benzoyl-3-methylcyclopropane-1,1,2,2-tetracarbonitrile
with water involved heterocyclization with participation of the carbonyl group and cis-cyano groups, leading to 8-methyl-3,6-dioxo-1-phenyl-2,7-diazatricyclo[3.2.1.04,8]octane-4,5-dicarbonitrile. Hydrolysis of 3-alkylcyclopropane-1,1,2,2-tetracarbonitrile followed both reaction paths to produce
mixtures of products, including 7-alkyl-4-amino-7-hydroxy-1,9-dioxo-3,8-diazatricyclo[4.3.0.01,5]non-3-ene-5-carbonitriles. In all cases, the three-membered ring was retained. 相似文献
