The pinacol rearrangement is essentially a dehydration reaction of an alcohol, specifically a diol. The following is an example of a pinacol rearrangement in which the (R,R)-diol (TBDMS is tert-butyldimethylsilyl) was allowed to react with 2,2 dimethylpropane (2,2-DMP) in the presence of boron trifluoride etherate at room temperature. This particular reaction was done in order to attain the acetone derivative.
Interestingly, instead of retaining its chirality, the product of the pinacol arrangement actually resulted in a racemic mixture. Subsequent derivatives of this product eventually yield benzophenone (hydroxyphenstatin), which, biologically, is a potent antitumor and antimitotic agent. Accordingly, hydroxyphenstatin has also been proven to inhibit tubulin assembly.
