Abstract
Esters of 5-amino-4-hydroxy-3-methylvaleric acids, which exist as pairs of diastereomers and are readily converted to the corresponding methyl-substituted 4-aminomethyl-4-butanolides or 5-hydroxy-2-piperidones, are obtained by reaction of esters of 3-methyl-4, 5-epoxy-2-pentenoic acid with amines and subsequent hydrogenation of the resulting esters of 5-amino-4-hydroxy-3-methyl-2-pentenoic acids.
