Abstract

Disclosed are novel condensed diazepinones of formula I ##STR1## wherein B is a fused ring selected from ##STR2## X is --CH-- or, when B is ortho-phenylene, X can also be nitrogen; A.sub.1 is C.sub.1 -C.sub.2 alkylene; A.sub.2 is C.sub.1 -C.sub.2 when it is in the 2-position relative to the saturated heterocyclic ring nitrogen or a single bond or methylene when it is in the 3- or 4-position; R.sub.1 is C.sub.1 -C.sub.3 alkyl; R.sub.2 is C.sub.1 -C.sub.7 alkyl, optionally hydroxy-substituted on at least one of its second to seventh carbon, or C.sub.3 -C.sub.7 cycloalkyl, optionally hydroxy substituted, or C.sub.3 -C.sub.7 cycloalkylmethyl; or R.sub.1 and R.sub.2 can, together with the nitrogen therebetween, be a 4- to 7-membered saturated monocyclic, heterocyclic ring which can optionally include an oxygen or N--CH.sub.3 ; R.sub.3 is hydrogen, chlorine, or methyl; R.sub.4 is hydrogen or C.sub.1 -C.sub.4 alkyl, R.sub.5 is hydrogen, chlorine or C.sub.1 -C.sub.4 alkyl; and Z is a single bond, oxygen, methylene or 1,2-ethylene; and NR.sub.1 R.sub.2 --N oxides and nontoxic, pharmaceutically acceptable addition salts thereof. Also disclosed are pyrrolobenzodiazepinone intermediates, pharm…
