RISSynthesis of pyrimido[4′,5′:2,3][1,4]thiazepino[ 7,6-b]quinolines, derivatives of a novel ring system Abstract: Several derivatives of the novel pyrimido[4′,5′:2,3]
Several derivatives of the novel pyrimido[4′,5′:2,3] [1,4]thiazepino[7,6-b]quinoline ring system have been
synthesized through cyclocondensation of 5-amino-6-methylpyrimidine-4-thiols 5a,b and 2-chloroquinoline-
One-Pot Synthesis of Functionalized Tetrahydro-1,4-thiazepines
One-pot synthesis of (5Z,7Z)-5-amino-7-(ethyl or arylimino)-2,3,4,7-
tetrahydro-1,4-thiazepine-6-carbonitriles from cyclocondensation of 2-((ethyl or arylamino)(
mercapto)methylene)malononitrile potassium salts or their methylated...
Synthesis of a novel fused tricyclic heterocycle, pyrimido[5,4- e ][1,4]thiazepine, and its derivatives
Sequential treatment of 5-bromo-2,4-dichloro-
6-(chloromethyl)pyrimidine with 2-aminothiophenol
and secondary amines afforded a series of 2-[(5-bromo-
2-chloro-6-aminopyrimidin-4-yl)methylthio]aniline ...
Synthesis of 2-substituted-4-methyl-5,13- dihydropyrimido[4',5':5,6][1,4]thiazepino[2,3- b]quinoxaline as a new heterocyclic system
2-Substituted-4-methyl-5,13-dihydropyrimido[4',5':5,6][1,4]thiazepino[2,3-b]quinoxalines
(7a-g), derivatives of a new heterocyclic system were synthesized through cyclocondensation of 2,4-dichloro-5-(chloromethyl) ...
Synthesis of a novel fused tricyclic heterocycle, benzo[b]pyridazino[4,3-f][1,4]thiazepin
A novel fused tricyclic heterocycles, 1-(5-amino-1,4-diphenyl-1,4-dihydrobenzo[b]pyridazino[4,3f][1,4]thiazepin-3-yl)ethanone was synthesized. The reaction of 1-(2-phenylhydrazono) propan-2-
one(1) with substituted 2-benzylidenemalonitriles2...
Synthesis of dihydrobenzo[b]pyrimido[4,5-e][1,4]thiazepines; derivatives of a novel ring system
Several derivatives of the novel dihydrobenzo[b]pyrimido[4,5-e][1,4]thiazepine ring system have been synthesised through the initial
heterocyclisation of 2,4-dichloro-5-(chloromethyl)-6-methylpyrimidine with o-aminothiophenol followed...
