5-(3-Substituted prop-cis-1-enyl)- and 5-(3-substituted prop-trans-1-enyl)- derivatives of 5H-dibenzo[a,d]cycloheptenes and 10,11-dihydro-5H-dibenzo[a,d]cycloheptenes and methods of making. The process of preparing the 5-(3-substituted prop-cis-1-enyl)- derivatives comprises hydrogenation of the appropriate 5-(3-substituted prop-1-ynyl)- derivatives in the presence of a noble metal catalyst. The 5-(3-substituted prop-trans-1-enyl)- derivatives can be prepared via treatment of the appropriate 5-(3-substituted prop-1-ynyl)- derivative with an alkali metal (e.g. sodium) in the presence of ammonia. Both the 5-(3-amino-cis- and 3-amino-substituted prop-trans-1-enyl)- derivatives exhibit antihistamine activity and are further useful in the treatment of, and/or palliation of, abnormal conditions occurring in mammals, related to the central nervous system. The remaining compounds have utility as intermediates for pharmacologically active compounds.
摘要:
An improved process for oxidizing an amine to the corresponding amine oxide with peracetic acid comprises carrying out the reaction in a distillation column, using as oxidant the gaseous mixture of peracetic acid and acetaldehyde resulting from the vapor-phase oxidation of acetaldehyde with oxygen. The amine is introduced in liquid form into the upper portion of the distillation column while the gaseous mixture of peracetic acid and acetaldehyde is simultaneously introduced into an intermediate location in the column. Reaction takes place within the column, with acetic acid and acetaldehyde being withdrawn as vapor from the top while a liquid comprising the amine oxide product is recovered from the base.
