Preparative-Scale, Facile Synthesis of (2R,4E)-2-Methyl-4-hexenal: A Key Intermediate of (2S,3R,4R,6E)-3-Hydroxy-4-methyl-2-methylamino-6-octenoic Acid (MeBmt)

Facile separation and mild acidic hydrolysis of the diastereomeric amides derived from 2-methyl-4-hexenoic acid and L-2-phenylglycinol are used in a rapid, preparative-scale synthesis of (2R,4E)-2-methyl-4-hexenal, a key intermediate of MeBmt.
