Methanesulfonic acid, 1,1,1-trifluoro-, anhydride with B,B-dibutylborinic acid

UsesDibutylboryl trifluoromethanesulfonate may be used in the following studies:Stereo- and regio-selective synthesis of erythro aldols. As a promoter for the solution and polymer-supported trichloroacetimidate-based glycosylations.Synthesis of β-alkoxy carbonyl compounds via one-step Mukaiyama aldol-type reaction.Aldol-type cyclization for the stereoselective synthesis of cyclic ethers.As a reagent for the formation of boron enolates. As a complexation aid for the isolation of 1-acyldipyrromethanes.As a promoter in [1,2]-Wittig reaction between aldehydes and O-benzyl or O-allyl glycolate esters, creating two contiguous stereocenters (1,2-diol) in good yield without the need for strong base.

General DescriptionDibutylboryl trifluoromethanesulfonate (Dibutylboron triflate, Bu2BOTf) is an organometallic reagent. It efficiently promotes the1,4-addition of benzylic and allylic organocopper reagents.
