We herein describe a chiral diboron-templated highly diastereoselective and enantioselective reductive coupling of isoquinolines that provided expedited access to a series of chiral substituted bisisoquinolines in good yields and excellent ee’s under mild conditions. The method enjoys a broad substrate scope and good functional group compatibility. Mechanistic investigation suggests the reaction proceeds

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
