The ene reaction of sulfur dioxide with enoxysilanes or with allylsilanes generates silyl sulfinates that can be brominated (Br2 or NBS) or chlorinated (NCS or Cl2) to produce the corresponding sulfonyl halides. They react with prima

The esters of β-oxoalkanesulfonic acids were shown by UV and 1H NMR spectroscopy to exist only in keto-form unlike b-oxocarboxylic acids. However, the possibility of existence of the enol form is manifested in the reaction of the ester of benzoylmethanesulfonic acid with diazomethane leading to the formation of O-methyl ester. In alkaline solutions of β-oxosulfoesters a reversible enolization is observed, and their salts have the enolate structure. The capacity to such enolization is retained also in the salts of β-oxoalkanesulfonic acids though it requires more rigid conditions. In an alkaline medium the esters suffer "acidic" splitting on storage.

This paper describes the development of several competitive inhibitors and mechanism-based inactivators of subtilisin BPN′. Various methyl arylakanesulfonates were prepared and shown to be either competitive inhibitors or selective methylating reagents fo
