The reaction of a silyl enol ether bearing a nitrogen atom with a hemiacetal vinylog in the presence of a catalytic amount of boron trifluoride etherate led to the corresponding ketoaldehyde. The cyclisation of the ketoaldehyde into azaspiroenone and

Efficient access to thermodynamically favoured silyl enol ethers deriving from α,α′-dienolizable ketones was produced via easy-made NEt3HCl-mediated isomerization of a regioisomeric mixture of O-silylated products. † deceased on 7 may 1997 § P

Condensation of enol ether 6 with methyl vinyl ketone led easily to ketoaldehyde 7 whose cyclisation afforded the azaspiranic enone 8, a key intermediate for the synthesis of the title alkaloids.

α,β-Unsaturated γ-lactams undergo regio- and stereoselective 1,3-dipolar cycloadditions with N-benzyl and N-methyl nitrones and can act as acceptors in conjugate addition of N-methylhydroxylamine. These reactions give access to highly functionaliz

A new Lewis acid-catalysed Michael-type addition of heterocyclic enol ethers to hemiacetal vinylogues 1 or to enones in the presence of a hydroxylic compound is described. The 1,5-keto acetals 3 so obtained have been studied with a view to synthetic
