In the title compound, C(9)H(12)Cl(2)N(4), the piperidine ring adopts a chair conformation. The electron delocalization of the molecule is indicated by the similar C⋯N distances within the triazine ring and by the double-bond character of the C=N triazine-piperidine connectivity. Weak intra-molecular C-H⋯N hydrogen bonds link the two rings within the mol-ecule, which exhibits a pseudo-mirror pl...

Microwave assisted new aldol condensation reaction of 1-oxo-1,2,3,4tetrahydrocarbazoles 1 with thiophene-2-carbaldehyde 2 in the presence of alcoholic KOH affords a single product 2-Thiophen-2-ylmethylene-2,3,4,9-tetrahydro-carbazol-1-one 3. 3 on irradiation with hydroxylamine hydrochloride yielded 3-Thiophen-2-yl-4,5-dihydro-10H-2-oxa-1,10-diazacyclopenta[a]carbazole 4 and 3 on irradiation wit...

Two new sulfated triterpenoid saponins, zygophylosides Q (1) and R (2), have been isolated from the barks of Zygophyllum fabago L. Their structures were elucidated as 3beta,24,28,30-tetrahydro-urs-20-ene-24-O-sulphonyl-3-O-[beta-D-glucopyranosyl]-30-O-beta-D-glucopyranoside and 3beta,24,28,30-tetrahydro-urs-20-ene-24-O-sulphonyl-3-O-[beta-D-xylopyranosyl]-30-O-beta-D-glucopyranoside, respective...

SKF83959 (3-methyl-6-chloro-7,8-hydroxy-1-[3-methylphenyl]-2,3,4,5-tetrahydro-1H-3-benzazepine), an atypical dopamine receptor-1 (D(1) receptor) agonist, has shown many D(1) receptor-independent effects, such as neuroprotection, blockade of Na(+) channel, and promotion of spontaneous glutamate release, which resemble the effects of the sigma-1 receptor activation. In the present work, we explor...

2-(Bromomethyl)-1-sulfonylaziridines were converted into novel 3-sulfonamido-2,3,4,5-tetrahydro-1,5-benzothiazepines upon treatment with 2-aminothiophenol in THF in the presence of K2CO3. Starting from 3-substituted 2-(sulfonyloxymethyl)aziridines, a regio- and stereocontrolled synthesis of trans-2-phenyl- and trans-4-(phenyl or propyl)-3-sulfonamido-2,3,4,5-tetrahydro-1,5-benzothiazepines was ...
