This communication reported the synthesis of novel C-6 substituted isofagomine analogues from easily accessible chiral nonracemic bicyclic lactams. These azasugars have potentially very interesting structure and are difficult to obtain by other metho

A series of polysubstituted pyrroles 3 have been synthesized efficiently in two or three steps starting from primary amines 1. The key step of this process is the bromocyclization of δ-dienamino esters 2. The chemoselectivity of this reaction is dis

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.

A study on the reactivity of 3,4-dihydro-2-pyridones 9, derived from (S)-phenylglycinol, toward different bases is presented. Using a catalytic amount of bases, the cis bicyclic lactams were obtained with excellent diastereoselectivities.

We have studied the reactivity of β-enaminoesters 1 (R 2 =OMe) or β-enaminoketone 1 (R 2 =Me), derived from ( S )-phenylglycinol, with activated acrylate derivatives. Substrates 1 (R 1 =Me) afforded by aza-annulation oxazololactams 2 and 3,4-dihydr

A series of 3-halo-2( 1H)-pyridinones 4 have been synthesized by treatment of δ-dienaminoesters 1 with N-halosuccinimide in basic medium. The chemoselectivity of the reaction is discussed.
