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, and R.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), or R.sup.3 is an esterified hydroxy group of the formula --OCO--R.sup.5, which represents a 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.1-4 alkoxy substituent(s), one or more halo substituent(s) and/or nitro substituent, a benzyloyloxy group, a xanthene-9-carbonyloxy group, an optionally substituted naphthoyloxy group, or an acyloxy group derived from a five- or six-membered heterocyclic carboxylic acid bearing optionally a halo substituent on the ring, are prepared by etherifying or esterifying a bicyclic compound of the general formula (II), ##STR2## wherein R.sup.1 and R.sup.2 are as defined above. The new compounds according to the invention possess anti-arrhythmic effects and can be applied to advantage in the therapy of cardiac rhythm disorders.
本发明涉及一种一般式(I)的新双环化合物,其中R1和R2各代表C1-6烷基基团,而R3是公式—CR4的醚化羟基团,其中R4是苯甲基基团、苯甲基基团或带有可选的苯基或三卤甲基取代基或一个或多个卤素取代基的苯基基团,或者R3是公式—OCO—R5的酯化羟基团,其中R5代表苯基(C1-5烷基)羰氧基基团、具有可选的卤素或一个或多个C1-4烷氧基取代基的肉桂酰氧基基团、具有可选的C1-4烷基、苯基或三卤甲基取代基或一个或多个C1-4烷氧基取代基、一个或多个卤素取代基和/或硝基取代基的苯甲酰氧基基团、苄基羧酸氧基基团、黄色素-9-羧酸氧基基团、可选取代的萘酰氧基基团或由带有环上可选卤素取代基的五元或六元杂环羧酸衍生的酰氧基基团。这些新化合物具有抗心律失常作用,并可以优势地应用于心律失常治疗中。这些化合物是通过醚化或酯化一般式(II)的双环化合物制备的,其中R1和R2如上所定义。
