New hydrogenated and didehydrogenated 1,2-diamines of quincorine and quincoridine
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 the bridgehead nitrogen.
