Article abstract of DOI:10.1248/cpb.56.738

A practical synthesis of a key intermediate for the proteasome inhibitor lactacystin from (R)-4-hydroxymethyl-2-phenyl-4,5-dihydrooxazol-4-ylmethyl acetate was established. (R)-4-Hydroxymethyl-2-phenyl-4,5-dihydrooxazol-4- ylmethyl acetate is a useful chiral building block for the synthesis of biologically active compounds containing α-substituted α-amino acid moieties.
