Abstract

A practical approach for enantiospecific synthesis of Beta-amino acids and related Beta-lactams was developed. The strategy was based on the mild oxidative cleavage of chiral dihydropyridones 4 conveniently prepared from an asymmetric three-component vinylogous Mannich reaction (VMR). The initially-obtained chiral -amino acid compounds can undergo further cyclization to give the corresponding chiral -lactams. Deprotection of the N-para-methoxybenzyl group can be performed at either the -amino acid or -lactam stages. This methodology provides convenient access to potentially important chiral building blocks for organic synthesis.
