A short synthetic route to protected α-methyl threonine 5 as a representative example for (protected) α-methylated α-amino-β- hydroxy acids bearing a stereogenic quaternary carbon center in α-position was developed. This multistep synthesis is based on th

An efficient synthetic route to all four stereoisomers of a-methylthreonine has been established. Each type of stereoisomer has been isolated in diastereomerically pure form and with an enantiomeric excess of at least 86% ee. The key step in this multi-st
