Ytterbium Metal-Promoted Reaction of Ketimines with Carbon Dioxide

Ketimines are reduced by ytterbium metal and reacted with carbon dioxide to give Yb salts of α-amino acids in good yields.

Keten. Part 17. Addition Reactions of Ketens with N-Phenyl Nitrones

The N-phenyl nitrones (1a), (4b), and (15) react with ketens in two totally different ways.Triphenylnitrone (4b) forms oxidolones (6) whereas (1a) and (15) form oxazolidinones (2) and (17).The differences appear to be caused by steric interactions in (1a) and (15) which distort the nitrone function and prevent the N-phenyl group adopting the conformation necessary for the oxindole-forming pathway.
