Diastereoselective synthesis of (S)- and (R)-α-phenylserine by a sulfinimine-mediated strecker reaction

A straightforward and efficient diastereoselective synthesis of (S)- and (R)-α-phenylserine is reported. The key step involves an asymmetric Strecker reaction of a chiral N-sulfinyl ketimine, which was obtained from the commercially available 2-hydroxyace

Stereoselective synthesis of α-substituted serines from protected erythrulose oximes

The additions of organolithium reagents to the C=N bond of several chiral oxime ethers derived from erythrulose afforded protected amino polyols with high diastereoselectivity. Four of the latter compounds have been convened into the α,α-disubstituted α-amino acids (R)-2-(-)-methylserine, (S)-2-(+)-methylserine, (R)-(+)-2-phenylserine and (R)-(-)-2-n-butylserine.

Diastereoselective additions of organolithium reagents to the C=N bond of protected erythrulose oxime ethers. Synthesis of enantiopure α,α-disubstituted α-aminoacids

The addition of organolithium reagents to the C=N bond of several erythrulose-derived chiral (E)- and (Z)-ketoxime ethers has been shown to be highly diastereoselective for the (E)-isomers. A chelated transition state has been proposed to explain this result. The addition products were converted into the two α,α-disubstituted α-aminoacids (R)-2-(-)-methylserine and (R)-(+)-2-phenylserine.

α-Hydroxymethylphenylglycine and α-hydroxymethylphenylalanine: Synthesis, resolution, and absolute configuration

Racemic α-hydroxymethylphenylglycine and α-hydroxymethylphenylalanine have been synthesized by selective hydroxymethylation of oxazolones derived from phenylglycine and phenylalanine, and resolved into enantiomers by fractional crystallization of their di
