process has been developed for the synthesis of functionalized N‐arylsulfonylaziridines bearing an alkoxycarbonyl, acyl, cyano, and carboxamide group at C2. The two‐step sequence involves addition of N,N‐dichloroarylsulfonamide to the appropriate olefin in the presence of Cu(acac)2, treatment of the resultant chlorosulfonamide with Na2SO3, followed by cyclization with NaOH to give the appropriate aziridine

The invention relates to a new group of aromatic sulphonamides derivatives of formula (I) and their synthesis and use for modulation of the activity of protein disulfide isomerase (PDI). More particularly, the invention provides small molecule inhibitors of PDI A1 that display antiplatelet, antithrombotic and anticancer activities.

Reaction of the title compounds with Phl=NSO2Ar (Ar = p-tolyl or p-nitrophenyl) in the presence of catalytic copper (II) triflate in acetonitrile gave the corresponding 2 and/or 3-substituted aziridine-2-carboxylates in generally; good yields. The latter, on reaction with nucleophiles, gave alpha-substituted alpha- or beta-amino acids depending on the pattern of substitution on the aziridine ring. (C) 1998 Elsevier Science Ltd.

Titanium Tetraiodide Mediated Reductive Opening of Aziridines, Leading to the Aldol and Mannich-Type Reactions
Reductive ring-opening of N-tosylazirindes was readily carried out with titanium tetraicidide to form the titanium enolates, which in turn were subjected to addition reaction with aldehydes or imines to give aldol or Mannich-type products in good yields.
