The imine Ph 2 CHN CHCO 2 Et, generated from benzhydrylamine and ethyl glyoxylate, is an excellent dienophile in aza-Diels-Alder reactions, giving diastereomerically pure cycloadducts in high yield.
The AB ring system found in the manzamine A and related alkaloids has been prepared from (-)-quinine by a short enantioselective route. The key step in the sequence is a ruthenium-catalysed ring-closing enyne metathesis re action which delivers a bicyclic diene in good yield. The functionality required for further elaboration of the AB system has been installed by sequential regioselective hydroboration...
