- Direct conversion of benzylic and allylic alcohols to phosphonates
-
Benzyl phosphonate esters often serve as reagents in Horner-Wadsworth- Emmons reactions. In most cases, they can be prepared from benzylic alcohols via formation of the corresponding halide followed by an Arbuzov reaction. To identify a more direct synthesis of phosphonate esters, we have developed a one-flask procedure for conversion of benzylic and allylic alcohols to the corresponding phosphonates through treatment with triethyl phosphite and ZnI2.

- Biomimic transformation of resveratrol
-
Resveratrol was treated with several kinds of peroxidases and inorganic reagents so as to prepare ε-viniferin. Among several inorganic reagents, which were investigated in this study, thallium(III) nitrate in methanol gave (±)-ε-viniferin in the yield of 68%. On the other hand, peroxidases did not lead to ε-viniferin, but some stilbenedimers such as pallidol, resveratrol trans-dehydrodimer, and leachianol F were obtained.
