WebApr 22, 2014 · The first synthetically useful approach to chiral N-sulfonyloxaziridines was based on the synthesis of camphor sulfonic acid derived imine 30, which can be selectively oxidized with oxone to give oxaziridine 31. ... Fontecave and co-workers also reported Lewis acid mediated activation of chiral N-alkyloxaziridines using ZnCl 2. WebCamphor is a central nervous system (CNS) stimulant with effects that range from mild CNS excitation to generalized seizures. Camphor is highly lipid soluble and easily crosses the blood–brain barrier.
