Abstract

The synthesis and enantioselective oxidations of [(8, 8-dihalocamphoryl) sulfonyl] oxaziridines[8, 8-dichloro-1, 7, 7-trimethyl-2'-(phenylsulfonyl) spiro [bicyclo [2.2. 1] heptane- 2, 3'-oxazinidine]] 13 are reported. These reagents are prepared in two steps from the (camphorylsulfony1) imine 4 by treatment of the corresponding azaenolate with electrophilic halogen sources followed by biphasic oxidation of the resulting dihalo imine 6-9 with m- ...
