Synthesis and reactions of partially reduced biisoquinolines

摘要

An improved synthesis of the 1,1′2,2′,3,3′,4,4′-octahydro-1,1′-biisoquinoline ring system is described. The reactivity of this system has been investigated, including the unusually high basicity of the parent compound and its N,N′-dimethyl derivative. The resolution of the parent compound has been achieved for the first time, along with the development of a straightforward method for assaying its enantiomeric purity.
