K. Kondo et al., Studies on development of sufficiently chemoselective N-acylation reagents: N-acyl-N-(2,3,4,5,6-pentafluorophenyl)methanesulfonamides, TETRAHEDRON, 56(32), 2000, pp. 5843-5856
A variety of storable N-acyl-N-(2,3,4,5,6-pentafluorophenyl)met (4a-e) prep
ared from N-2,3,4,5,6-pentafluorophenylmethanesulfonamide (3), have been de
veloped after systematic research on the structure-reactivity relationship
and were found to serve as N-acylation reagents exhibiting sufficiently goo
d chemoselectivity. (C) 2000 Elsevier Science Ltd. All rights reserved.
