Abstract: The invention relates to new anti-arrythmic azabicyclo[3.3.1]nonanes of the general formula (I) ##STR1## wherein R.sup.1, R.sup.2 and R.sup.3 are C.sub.1-4 alkyl groups which are the same or different, or one of them is a benzyl group and the others are C.sub.1-4 alkyl groups, andR.sup.4 is a hydroxy group, or an etherified hydroxy group of the formula --OR.sup.5, or an esterified hydroxy group of the formula --OOCR.sup.6, in which the esterifying groupR.sup.5 is a phenyl or benzyl group which optionally each can have a trihalomethyl substituent or one or more halogen or C.sub.1-4 substituents, or is a diphenyl or benzhydryl group, and the esterifying groupR.sup.6 is a C.sub.1-8 alkyl or a C.sub.3-6 cycloalkyl group, or a phenyl or benzyl group which optionally each can have a halo-substituent or one or more C.sub.1-4 alkyl, C.sub.1-4 alkoxy, nitro or phenyl substituents, or is an optionally halogenated or hydrogenated naphthyl group, or a cinnamyl group optionally substituted by a halogen atom or C.sub.

Abstract: New bicyclic compounds of the general formula (I), ##STR1## wherein R.sup.1 and R.sup.2 each represent a C.sub.1-6 alkyl group, andR.sup.3 is an etherified hydroxy group of the formula --CR.sup.4, wherein R.sup.4 is benzyl group, benzhydryl group or a phenyl group bearing optionally a phenyl or a trihalomethyl substituent or one or more halogen substituent(s), orR.sup.3 is an esterified hydroxy group of the formula --OCO--R.sup.5, which representsa phenyl-(C.sub.1-5 alkyl)-carbonyloxy group,a cinnamoyloxy group having optionally a halogen or one or more C.sub.1-4 alkoxy substituent(s),a benzoyloxy group having optionally a C.sub.1-4 alkyl, phenyl or trihalomethyl substituent or one or more C.sub.
