P. Mastrorilli et al., Aerobic oxidative cleavage of pinanediols by cobalt(II) acetylacetonate inthe presence of 2-methylpropanal, J MOL CAT A, 156(1-2), 2000, pp. 279-281
The catalytic system made up of cobalt(II) acetylacetonate, 2-methylpropana
l and dioxygen (or air) facilitated the oxidative cleavage of (1S,2S,3R,5S)
-(+)-pinanediol 1a and (1 R,2R,3S,SR)-(-)-pinanediol 1b to enantiomerically
pure cis-pinonic acids 4a-b. (C) 2000 Elsevier Science B.V. All rights res
