Application of 1,2:5,6-di-O-cyclohexylidene-d-mannitol as the chiral director in Matteson’s asymmetric homologation
摘要:
1,2:5,6-Di-O-cyclohexylidene-D-mannitol is the good chiral director in Matteson's asymmetric homologation as indicated by the high enantiomeric excesses (ee's) of the secondary alcohols produced by treatment of the homologation products with alkyllithium or Grignard reagents followed by oxidation.
