Abstract: (3R,4R)-4,7,7-trimethyl-6-oxabicyclo [3.2.1] octane-3,4-diol was prepared by reaction of α-pinene with 30 % H2O2 in presence of dodecyl pyridinium peroxyopolyphosphotungstate catalyst (Cat-PW4). The effects of different reaction factors on the conversion rate and selectivity were investigated. The optimal conditions are as follows: α-pinene, 12.8 mmol; chloroform as solvent, 5 mL; reaction temperature, 40 ℃; Cat-PW4 as catalyst, 0.2 g; 30 % H2O2, 3.3 mL; reaction time, 3 h. Under these conditions, the conversion rate of α-pinene reached 94.7 %, and the selectivity for the title compound reached 39.8 %. The product existed both in aqueous phase and organic phase and could be isolated from reaction mixtures by extraction and re-crystallization. It was structurally identified by means of IR, UV, 1H NMR, 13C NMR, GC/MS, and HR-ESI-MS. Its yield and purity were 11 % and 98 %, respectively.

Key words: (3R,4R)-4,7,7-trimethyl-6-oxabicyclo[3.2.1] octane-3,4-diol, α-pinene, H2O2, dodecyl pyridinium peroxyopolyphosphotungstate
