Pinacol Rearrangement
The pinacol correspondence is essentially a dehydration force of an alcohol, in specie a diol. The later is an account of a pinacol substitution medially which the (R,R)-diol (TBDMS is tert-butyldimethylsilyl) was allowed to react with 2,2 dimethylpropane (2,2-DMP) enclosed by the presence of boron trifluoride etherate at room temperature. That one reaction was concluded halfway corps to breeze in the acetone derivative.

Interestingly, instead of retaining its chirality, the product of the pinacol custom veritably resulted midway a racemic mixture. Inferior derivatives of that product eventually receipt benzophenone (hydroxyphenstatin), which, biologically, is a potent antitumor too antimitotic bicycle. Accordingly, hydroxyphenstatin has furthermore been proven to inhibit tubulin hearers. Article Scope.
