Ha, Deok Chan published the artcileN-Trimethylsilylimines: applications to the syntheses of β-lactams, Formula: C8H16O2, the publication is Journal of the American Chemical Society (1984), 106(17), 4819-25, database is CAplus.
Ester enolates and N-trimethylsilylimines react to afford β-lactams. The stereochem. course of the reaction depends on the ester enolate geometry. Thus, (E)-enolates give mainly cis β-lactams while (Z)-enolates give ∼1:1 mixtures of cis and trans β-lactams. The use of HOCHMeCH2CO2Et as the ester component gives β-lactams of potential use in carbapenem synthesis. The differences in the behavior of N-trimethylsilyl and N-arylimines in the ester-imine condensations are also discussed.
