- Studies on development of sufficiently chemoselective N-acylation reagents: N-Acyl-N-(2,3,4,5,6-pentafluorophenyl)methanesulfonamides
-
A variety of storable N-acyl-N-(2,3,4,5,6-pentafluorophenyl)methanesulfonamides (4a-e) prepared from N-2,3,4,5,6-pentafluorophenylmethanesulfonamide (3), have been developed after systematic research on the structure-reactivity relationship and were found to serve as N-acylation reagents exhibiting sufficiently good chemoselectivity.

- A versatile synthon for chemoselective N-acylation reagents, 2-fluoro-N-mesylaniline
-
2-Fluoro-N-mesylaniline 3b undergoes various N-acylalions easily to give 2-fluoro-N-acyl-N-mesylanilines 4b-8b, which function as good chemoselective N-acylation reagents, especially for benzyloxycarbonylation.
