Sulfinate Alkylation Diversification Kit

Product overview:

The sulfinate alkylation reaction described by Prof. Baran is a powerful late stage functionalization tool. Our kit allows to conveniently produce in one step 6 different analogues of a lead compound in mg quantities. Each reaction vial contains 100 µmol of sulfinate alkylation reagent (pre-weighed) and a stirring bar to react with 50 µmol of substrate.  C-H functionalization will primarily occur on electron-deficient heteroarenes at one or several positions.

Standard Protocol:

Several solvents or solvent mixtures can be used to perform the reaction (DMSO, DMSO/H2O/TFA, CHCl3/H2O/TFA… ). A solution of substrate is made with 300 µmol of substrate in 2.1 ml selected solvent. 350 µl is added in each vial followed by 20.8 µl of TBuOOH (70% in water). The reactions are allowed to stir at 50°C for 12-24 hours.
