✦ Synopsis
Both diastereomers of racemic y-hydroxynorvaline were prepared from 4-penten-2-01 to illustrate a new general method for stereoselective synthesis of either eryrhro-or three-1,3-amino alcohol systems from a single precursor.
Non-proteinogenic y-hydroxy-a-amino acids are an important class of naturally occurring amino acids.' We

Enantioselective Synthesis of γ-Hydroxynorvaline. -Key step in the synthesis of title compound (VI) is the diastereoselective alkylation of chiral Schiff base (I) with iodide ( II) obtained by ring opening of (S)-propylene oxide using Tms-I at low temperatures. -(JACOB, M.; ROUMESTANT,
The Pd-catalyzed isomerization of 5-vinyloxazolines was utilized for the stereoselective synthesis of D-erythro -and L-threo -spinganine triacetate. A hydroboration/Suzuki coupling sequence was employed to elongate the hydrophobic chain.
DL-erythro-sphingosine and DL-threo-sphingosine specifically labelled with 3H in positions 4 and 5 were prepared. The synthesis of these compounds was based on a modification of a procedure published by Grob and Gadient. Quantitative separation of the sphingosines from acetylenic impurities was acco

All four isomers of substituted 3-alkylthio-4-hydroxybutenes have been synthesised: both the geometry of the double bond and the relative stereochemistry of the two chiral centres are controlled. We have recently reported' the synthesis of the unstable allylic sulphide (4) via a three stage allyli
