Af. Barrero et al., PREFERENTIAL OXIDATION REACTIONS OF THE SIDE-CHAIN OF UNSATURATED LABDANES, Bulletin de la Societe chimique de France, 130(5), 1993, pp. 700-707
In order to find experimental conditions for the regioselective degrad
ation of the side chains of different labdanes related to (Z)-communic
acid 2b some oxidation reactions have been studied. Thus, the reactio
ns of the labdatrienes 2b, 9 and the labdadienes 10, 11 with ozone and
with the OSO4-NaIO4 system, and the treatment of 9 with m-CPBA (3-chl
oroperoxybenzoic acid) are described.
