摘要:
This disclosure describes novel compounds of the formula ##STR1## wherein R.sub.1 and R.sub.2 each independently represent hydrogen, halo having an atomic weight of about 19 to 36, lower alkyl, straight chain lower alkoxy, amino, nitro or trifluoromethyl, andX represents ##STR2## which are useful as minor tranquilizers and sleep inducers.
摘要:
1,3,3-Trimethyl-2-oxabicyclo[2,2,2]octan-6-ones are prepared by first epoxidizing .alpha.-terpineol with a peracid and thereafter oxidizing the resulting product with an appropriate oxidizing agent.
摘要:
The present invention provides new pyridazinones of the formula ##STR1## where R is alkyl;R.sub.1 and R.sub.2 are halo, alkyl, alkoxy, amino; nitro or trifluoromethyl;R.sub.3 is hydrogen, hydroxy, or acyloxy;R.sub.4 is hydrogen or alkyl; andR.sub.5 is hydroxy or acyl;which are useful as central nervous system depressants.

摘要:
5,5,7,7-tetramethyl-3-substituted or unsubstituted-phenylfuro[3,4-e]-as-triazines and corresponding 4-oxides, e.g., 5,7-dihydro-5,5,7,7-tetramethyl-3-phenylfuro[3,4-e]-as-triazine and 5,7-dihydro-5,5,7,7-tetramethyl-3-phenylfuro[3,4-e]-as-triazine-4-oxide, are prepared from 2,2,5,5-tetramethyl-3,4(2H,5H)-furandione-3-hydrazone-4-oximes and are useful as sleep inducers and minor tranquilizers.
摘要:
Substituted or unsubstituted-3-pyridyl and pyridyl-N-oxide-furo[3,4-e]-as-triazines, e.g., 5,7-dihydro-3-(2-pyridyl)-5,5,7,7-tetramethyl-furo[3,4-e] -as-triazine are prepared by reacting 2,2,5,5-tetramethyl-3,4(2H,5H)furandiones with substituted or unsubstituted pyridylcarboxamidic acid hydrazides and are useful as sleep inducers and minor tranquilizers.
