4,1-Benzoxazepines and compositions

Abstract

4,1-Benzoxazepines of the following formula are central nervous system drugs: ##STR1## wherein R is hydrogen or C.sub.1 to C.sub.5 alkyl; X is hydrogen, halogen, or nitro; Y is phenyl, 2-halophenyl, 4-halophenyl, 2-trifluoromethylphenyl, or pyridyl; and ##STR2## is a group of the formula: ##STR3## (wherein Q is oxygen, sulfur, or hydrazono, with a proviso that, when Y is phenyl or 2-halophenyl and R is hydrogen, Q is neither oxygen nor sulfur; R.sup.1 is hydrogen, halogen, C.sub.1 to C.sub.5 alkyl, C.sub.1 to C.sub.5 alkylthio, 5- or 6-membered heterocycle or C.sub.1 to C.sub.5 alkyl substituted by a substituent selected from the group consisting of halogen, hydroxy, mercapto, C.sub.1 to C.sub.5 alkoxy, C.sub.1 to C.sub.5 alkanoyloxy, C.sub.1 to C.sub.5 alkylthio, C.sub.7 to C.sub.9 aralkyldithio, C.sub.2 to C.sub.10 dialkylamino, C.sub.3 to C.sub.15 dialkylaminoalkoxy, C.sub.3 to C.sub.15 dialkylaminoalkylthio, and 5- or 6-membered heterocycle; R.sup.2 is C.sub.1 to C.sub.5 alkyl; and R.sup.3 is C.sub.1 to C.sub.5 alkyl or C.sub.3 to C.sub.10 dialkylaminoalkyl; with a proviso that when R.sup.1 is C.sub.1 to C.sub.5 alkyl and R is hydrogen, Y is neither phenyl nor 2-halophenyl).
