A series of N-alkyl-2-oxoalkanesulfonamides have been synthesized by reacting silyl enol ethers with N-alkyl-sulfamoyl chlorides. Their reactivity towards electrophiles was investigated in order to explore the regio-and stereoselectivity of the process. 2-Oxoalkanesulfonamides were used to prepare 5-(methylsulfamoyl)-1,4-dihydropyridines derivatives.

Highly enantioselective transfer hydrogenation of racemic α-substituted β-keto sulfonamides <i>via</i> dynamic kinetic resolution
Highly enantioselective transferhydrogenation of β-keto sulfonamides was developed via dynamic kineticresolution using a chiral Ru(II) catalyst with an azeotropic solution of HCO2H/Et3N as a hydrogen donor, affording α-substituted β-hydroxyl sulfonamides in good yields with excellent diastereo- and enantioselectivities. This method is featured with mild conditions, easy operation, and a broad substrate
