    Azaindole derivatives (1972)

    Notes: Abstract Electrophilic substitution reactions — cyanomethylation, bromination, nitration, and the Mannich reaction- in the 5-azaindole series were studied. It is shown that, despite the literature data, 5-azaindole behaves like the isomeric 4- and 7-azaindoles in these reactions. Conditions that make it possible to synthesize various 3-substituted 5-azaindoles in high yields were found.

    Some reactions of 2-chloro-3-(β-chloroethyl)-4,6-dihydroxypyridine (1970)

    Notes: Abstract The chemical properties of 2-chloro-3-(β-chloroethyl)-4,6-dihydroxypyridine (I) have been studied. It has been shown that this compound, which is relatively stable in acids and in neutral and, particularly, in alkaline media, readily splits off hydrogen chloride under mild conditions and is converted into derivatives of 2, 3-dihydro-5-azabenzofuran. The dehalogenation of I in an acid medium yielded 3-(β-chloroethyl)-4, 6-dihydroxypyridine, which was converted into 4, 6-dichloro-3-(β-chloroethyl)pyridine and into 6-chloro-4-methoxy-3-vinylpyridine.

    Notes: Abstract The reaction of 2,4-dichloro-5-(β-chloroethyl)pyridine with ammonia and N-ethylaniline, leading to the formation of 5-azaindoline derivatives, has been studied. The processes of the formation of 6-phenylamino and 6-(N-alkyl-N-phenylamino) derivatives of 7-azaindoline, 5-azaindoline, and 5,7-diazaindoline taking place with N-dealkylation and without it have been compared.

    Notes: Abstract A new synthesis of 5-azaindole and its derivatives has been developed, which consists in the reaction of 6-oxo-2, 3-dihydro-5-azabenzofuran with primary amines, followed by elimination of the substituent in the 6-position and dehydrogenation of the resulting 5-azaindolines with a palladium catalyst. Electrophilic substitution reactions in the 6-oxo-5-azaindoles are investigated.
