Single or Synergistic Kinetic Resolutions of Chiral Allylalanes: Two Complementary Routes for the Asymmetric Synthesis of Syn Homoallylamines

Two strategies based on kinetic resolution(s) of chiral alanes and providing enantioenriched syn homoallylamines are reported. The first implies a single kinetic resolution of the alane using camphor; the second requires two sequential kinetic resolutions using the synergistic combination of (-)-camphor/(R)-tert-butylsulfinamide-derived imines. This syn selectivity, specific to the use of allyaluminum, opens the way to the preparation of valuable building blocks as illustrated by the synthesis of (+)-epilupinamine.

Method for synthesizing S-shaped amino compound

The invention discloses a method for synthesizing S-shaped amino compound, namely, S-alpha-cyclopentyl(phenyl)methylamine. The method includes the steps of using cyclopentyl phenyl ketone as a raw material, allowing cyclopentyl phenyl ketone to react with

Facile asymmetric synthesis of α-amino acids employing chiral ligand-mediated asymmetric addition reactions of phenyllithium with imines

A three-step methodology involving an external chiral ligand-mediated asymmetric addition of phenyllithium to an anisidine imine, oxidative removal of N-PMP group, and finally oxidative conversion of the phenyl group to a carboxyl group provides a facile synthesis of optically pure α-amino acid derivatives beating a bulky α-substituent.
