    • These could possibly be the corresponding glycosyl selenoxide and the glycosyl selenone. One referee suggested that formation of the lactol 21, in preference to any methyl glycoside, might arise from an Se to O rearrangement to produce a glycosyl selenenate which then hydrolyses. However, we currently have no evidence to support this mechanism, and presume that the lactol may simply arise from acid catalysed decomposition of the glycosyl selenoxide on silica.

    • Our observations here are in contrast with a report on the use of glycosyl selenoxides as glycosyl donors when produced by oxaziridine oxidation of selenoglycosides. See Ref. 3.
