Highly enantioselective rhodium-catalyzed hydrogenation of (Z)-N-sulfonyl-α-dehydroamido boronic esters is realized for the first time using a JosiPhos-type ligand. This method has enabled convenient synthesis of a series of enantio-enriched N-sulfonyl-α-amido boronic esters in good yields and excellent enantioselectivities (up to 99% ee).

An extensive exploration of the structure-activity relationship of a trisubstituted sulfonamide series led to the identification of 39, which is a potent and selective CB2 receptor inverse agonist [K i(CB2) = 5.4 nM, and Ki(CB1) = 500 nM]. The functional properties measured by cAMP assays indicated that the selected compounds were CB2 inverse agonists with high potency values (for 34, EC50 = 8.2 nM, and for 39, EC50 = 2.5 nM). Furthermore, an osteoclastogenesis bioassay indicated that trisubstituted sulfonamide compounds showed great inhibition of osteoclast formation.

Hg cathode-free electrochemical detosylation of N,N-disubstituted p-toluenesulfonamides was successfully carried out by a constant current electrolysis using an undivided cell equipped with a platinum cathode and a magnesium anode in the presence of an arene mediator. The deprotection proceeded efficiently and selectively under neutral and mild conditions with a stoichiometric amount of electricity without the use of an Hg cathode to obtain the corresponding secondary amines in good to excellent yields.
