Journal ArticleDOI

Stereoselective syntheses of substituted 5,6-dihydro-2(1H)-pyridinones in polyphosphate media

TL;DR: In this article, the scope of the condensation of 3-alkenamides with aryl aldehydes in several phosphate media is examined, and a rationale is proposed regarding gamma-lactam versus delta-Lactam formation.
Journal ArticleDOI

Stereocontrolled construction of condensed gamma-lactam ring-systems by cationic cyclizations - rearrangement of a gamma-lactam to a delta-lactam

TL;DR: In this article, a new condensation of 3-alkenamides with benzaldehyde in acidic media, notably polyphosphoric acid, leads to gamma-lactam rings with high regio-and stereocontrol.
Journal ArticleDOI

Enantiospecific synthesis of (-)-tabtoxinine .beta.-lactam

TL;DR: Key features of the synthetic route include preparation of a new γ-cation amino acid synthon and its use as an electrophile and the one pot conversion of methyl sulfide to the Cbz-protected amine via stereoselective sulfilimine rearrangement and chemoselectives lactone ring opening in spiro lactam.
