39 - 160Diastereoselective Ring Opening of Limonene Oxide with WaterCatalyzed by β-Ketophosphonate Complexes of Molybdenum(VI).— The hydrolytic ring opening of limonene oxides (I) and (II) in the presenceof chiral camphor ketophosphonate derived Mo-complexes such as (III) isinvestigated. The cis-isomer (I) is readily converted to the diol, whereas thetrans isomer (II) remains unreacted, thus providing a method for the kineticseparation of the trans diastereomer. — (SALLES, LAURENT; NIXON, AN-DREW F.; RUSSELL, NICHOLAS C.; CLARKE, RUSSELL; POGORZELEC,PETER; COLE-HAMILTON, DAVID J.; Tetrahedron: Asymmetry 10 (1999) 8,1471-1476; Sch.
