(-)-(E)-Crotyldiisopinocampheylborane was employed in a highly diastereoselective and enantioselective synthesis of the gamma-hydroxy-beta-methyl-alpha-aminobutanoic acid moiety of nikkomycin B. A protected derivative of this N-terminal amino acid residue was condensed with uracil polyoxin C benzyl ester to provide, on deprotection, the antifungal agent nikkomycin B.
