摘要

Four new members of the family of 1, 2-diamines of quincorine and quincoridine have been synthesized, being hydrogenated and didehydrogenated at the C10–C11 fragment. The alkynes, containing an additional amino group at C9, are potentially useful building blocks for cross-coupling reactions. Additional investigations concerning the chemical properties of the molecules point to a significant impact of the remote C5 substituent on the basicity of ...
