[reaction: see text] Efficient synthesis of enantiomerically pure (-)-statine was achieved with the stereoselectiveintramolecular conjugate addition of the hydroxyl group tethered to the amino group of a configurationally stable N-Boc-L-leucinal derivative.

The N-hydroxymethyl derivatives of α-amino aldehydes 1 were utilized for the effective synthesis of several β-amino-α-hydroxy acid derivatives in a one-potprocess starting from the corresponding α-amino aldehydes. Properly protected methyl esters 3 were prepared in 65–79% yields from α-amino aldehyde derivatives 1 with more than 20:1 stereoselectivity. The application of suitably protected β-amino-α-hydroxy
