Js. Ng et al., A PRACTICAL SYNTHESIS OF AN HIV PROTEASE INHIBITOR INTERMEDIATE - DIASTEREOSELECTIVE EPOXIDE FORMATION FROM CHIRAL ALPHA-AMINOALDEHYDES, Tetrahedron, 51(23), 1995, pp. 6397-6410
A practical and efficient synthesis of an HIV protease inhibitor inter
mediate has been developed based on the diastereoselective epoxide for
mation from a chiral alpha-aminoaldehyde and an in situ generated halo
methyllithium reagent.
