Secondary homochiral lithium amides derived from α-methylbenzylamine undergo highly diastereoselective conjugate additions to a range of α,β-unsaturated esters. The corresponding β-aminoacids are readily liberated by successive N-debenzylation and ester hydrolysis, furnishing (R)-β-amino butyric acid, (R)-β-amino pentanoic acid, (S)-β-leucine, (R)-β-amino octanoic acid, (S)-β-phenylalanine, (S)-β-tyrosine
ketone gave, after some structural modifications, β,β -diamino ketals. Mannich-type reactions of these diamines with an aldehyde led, with high diastereoselectivity, to trisubstituted piperidines. Another highly stereoselective Mannich cyclization, with an N-acyliminium ion generated in situ from the corresponding imide, allowed the preparation of original polycyclic bispidine derivatives. The antinociceptive

a typical Barton decarboxylation procedure. While carrying out this reaction in presence of a N,N-disubstituted β-amino acid derivative, the decarboxyphenyl rearranged derivative is obtained, as well as in presence of β-N,N-acylamide. On the other hand, secondary amines give the β-lactam derivative without rearrangement, as well as N-Fmoc derivatives give the normaldecarboxylation reaction. In regards
