H. Abe et al., Preparation of iodo-induced 1,3-oxathiane compounds via intramolecular Pummerer rearrangement of 2-benzylsulfinyl-bicyclo[2.2.1]hept-5-ene, HETEROCYCLE, 52(1), 2000, pp. 465-470
Iodooxathianes (2a and 2b) were prepared from the gamma,delta-unsaturated s
ulfinyl compound (1) via the iodonium-promoted intramolecular Pummerer reac
tion. A two-step conversion of 1 into 2a and 2b involving iodohydrination a
nd the Pummerer rearrangement was also achieved.
