Malonyloxyborohydride,a hydroboration reagent,is prepared by reaction of malonic acid and sodium borohydride,and is used to react with dihydromyrcene in THF.

When cis pinane was converted completely, the selectivity of dihydromyrcene was over 50% while that of thermal cracking is much lower.

This paper studied the effects of the reaction temperature,the flow of N 2 and the contact time on conversion of pinane and selectivity to dihydromyrcene under empty tube (no cat)and ambient pressure.

Hydroxy in dihydromyricetin(DMY)was esterified with lauroyl chloride and dihydromyricetin laurate (DMYL) was synthesized in this investigation.
