Seven morpholin derivatives were synthesized (compounds 1-7) and their behavioural effects were evaluated; the elements considered were locomotor activity, motor coordination, catalepsy, stereotyped behaviour and antinociception. All the compounds, at doses of 10-20-40 mg/kg/i.p., induced a reduction of all behavioural elements without a significant antinociceptive effect. These results indicate that these morpholin derivatives affect the central nervous system. 相似文献

The synthesis of 1,2-dihydro-1-oxo-as-triazino[4,5-a]indoles was achieved by rearrangement of 2-oxadiazolyl-indoles under alkaline conditions or by cyclisation of indole-N-ethoxymethylid-ene hydrazides. The cyclisation of the N-carbethoxyhydrazone of the indole-2-carboxaldehyde gave the 1,2-dihydro-1-oxo-as-triazino[4,5-a]indole. The study of the lactim-lactam tautomerism was accomplished using the ir and nmr spectra. 相似文献

Pyrrole hydrazides and hydrazones were synthesized from pyrrole-2-carboxylic acid and pyrrole-2-carboxaldehyde, The 2-pyrrolyloxadiazoles and thiadiazoles were obtained by cyclising the pyrrole hydrazides with phosphorus oxychloride and tetraphosphorus decasulphide. These derivatives have been used for the synthesis of pyrrolo[1,2-d]-1,2,4-triazines by cyclisation or rearrangement. 相似文献

1,4-Dioxo-1,2,3,4-tetrahydro-l,2,4-pyrrolo[l,2-~-1,2,4-triazine (1) was synthesized either by cyclising the N-carbethoxyhydrazide of pyrrole-2-carboxylic acid (2) or by alkaline rearrangement of 2-(2-pyrrolyl>5-oxadi- azolone (3). The methylation reactions of the dilactam 1 were achieved with dimethyl sulfate or diazomethane and afforded mixtures of U-methylated and N-methylated derivatives which were isolated by gas chromatography and the structures of which were assigned using ir and 1H nmr spectra. 相似文献

The synthesis of 1,2,4-triazolo[4,3-a] and [2,3-a]pyridines 7, 8 was achieved by cyclization of 2-hydrazino-8-nitropyridine 3a with formic acid. The 4,5,6,7-tetrahydro-1,2,4-triazolo[2,3-a]pyridine 13 and 8-amino-1,2,4-triazolo[2,3-a]pyridine 9 were obtained by catalytic hydrogenation. The reduction of triazolo pyridine 8 using stannous chloride led to the intermediate compound 10 which with acetic anhydride afforded 8-acetylamino-5-chloro-1,2,4-triazolo[2,3-a]pyridine 10a . The structure of the derivatives was determined by 1H-nmr (DMSO-d6). 相似文献
