  • 3-carbalkoxyamino-5-(alpha-aminopropionyl)-5H-dibenz[b,f]azepines and method for their making
    Patent number: 5192760
    Abstract: New 3-carbalkoxyamino-5-(alpha-aminopropionyl)-5H-dibenz[b,f]azepines of formula I and their pharmaceutically acceptable salts were found to be suitable actives for the treatment of cardiac arrhythmia. Previously unknown 3-carbalkoxyamino-5-(alpha-halogenpropionyl)-5H-dibenz[b,f]azepines are obtained from 3-carbalkoxyamino-5H-dibenz[b,f]azepines by reaction with alpha-halogenpropionyl halides. Through their reaction with ammonia, primary amines or secondary amines, the new 3-carbalkoxyamino-5-(alpha-aminopropionyl)-5H-dibenz[b,f]azepines are obtained, which can be optionally converted into their pharmaceutically acceptable acid addition salts.

  • 3-carbalkoxyamino-5-aminoacyl-5H-dibenz[b,f]azepines, and methods for making
    Patent number: 5116974
    Abstract: New 3-carbalkoxyamino-5-aminoacyl-5H-dibenz[b,f]azepines and their pharmaceutically acceptable acid addition salts, and methods for their synthesis are described. These compounds are useful as antiarrhythmic agents in the treatment of heart disorders. The new compounds are made by reacting a 3-carbalkoxyamino-5-halogenacyl-5H-dibenz[b,f]azepines with an amine to form the desired target product, which can be optionally converted into its pharmaceutically acceptable acid addition salt.
