  Synthesis of (−)‐Cytoxazone and (+)‐epi‐Cytoxazone: The Chiral Pool Approach

  摘要：

  Immunomodulator (-)-cytoxazone and its epimer (+)-epi-cytoxazone were synthesized starting from (D)-(-)-4-hydroxyphenylglycine. Homologation of the amino acid was achieved via the corresponding aldehyde, by a cyanohydrin reaction. The racemization of highly sensible amido aldehyde was efficiently suppressed when the oxidation of the parent aminoalcohol was performed by a modified Dess-Martin procedure.

• Catalytic Asymmetric Hydrogenation of N-Boc-Imidazoles and Oxazoles

  日期：2011.5.18

  Substituted imidazoles and oxazoles were respectively hydrogenated into the corresponding chiral imidazolines and oxazolines (up to 99% ee). The highly enantioselective hydrogenation was achieved by using the chiral ruthenium catalyst, which is generated from Ru(eta(3)-methallyl)(2)(cod) and a trans-chelating chiral bisphosphine ligand, PhTRAP. This is the first successful catalytic asymmetric reduction of 5-membered aromatic rings containing two or more heteroatoms.
