Aza-annulation of β-enaminolactones: application to the synthesis of enantiopure difunctionalized bicyclic lactams

Alladoum, Jeanne,Toum, Valérie,Hebbe, Séverine,Kadouri-Puchot, Catherine,Dechoux, Luc

, p. 617 - 619 (2009)

Diastereoselective aza-annulation of seven-membered β-enaminolactones 2 gives access to bicyclic heterocyles 5. Fragmentation of molecule 5a with lithium methoxide affords cis or trans bicyclic lactams 8 with excellent stereoselectivities.
