摘要
The insufficient diastereoselectivity and generality, which are the main problems of the 'acetate' aza - aldol reaction, can now be addressed through the reaction of the lithium enolate of endo-O-trimethylsilyl acetyl isoborneol with various N[(p-tolylsulfonyl)alkyl] carbamates (see scheme). This development provides record levels of asymmetric induction in a new Mannich-type synthesis of β-amino acids which is general even for inherently enolizable imino compounds.
