Stereodivergent approach to both syn- and anti-isomers of γ-amino-β-hydroxy acids: (3S,4S)- and (3R,4S)-AHPPA derivatives

A stereodivergent approach employing an N-hydroxymethyl group has been utilized to produce both diastereomeric derivatives of (3S,4S)-AHPPA 3 and (3R,4S)-AHPPA 4, via an intramolecular conjugate addition and an intramolecular epoxidation, respectively. Th

A NOVEL SHORT AND EFFICIENT ASYMMETRIC SYNTHESIS OF STATINE ANALOGUES

The statine analogues 1a-c have been obtained in high optical purity via addition of chiral acetate enolate 4 to the α-aminoaldehydes 5a-c, followed by transesterification.

Stereospecific Synthesis of N-Protected Statine and Its Analogues via Chiral Tetramic Acid

The condensation of a chiral N-protected amino acid with Meldrum's acid in the presence of isopropenyl chloroformate (IPCF) and of 4-N,N-dimethylaminopyridine (DMAP) has been examined.The cyclisation of the reaction product, by heating in an organic solve
