a-Hydroxynaphthylthiophthalimide (1) is a suitable precursor of the reactive ortho-thioquinone 2, which can be generated in situ and trapped by glycals. The reaction is an inverse electron-demand [42] cycloaddition that occurs in a totally regioselective and highly stereoselective way. A series of d
## Abstract Fluorideβdirected methylation of the aryl hydroxyl of hydroxyphenyl glycosides with radioactive methyl iodide allows the incorporation of label under mild conditions that preserve the glycosidic link. The effectiveness of this approach has been demonstrated by the synthesis of two ^14^C
