A versatile synthon for chemoselective N-acylation reagents, 2-fluoro-N-mesylaniline

摘要

2-Fluoro-N-mesylaniline 3b undergoes various N-acylattions easily to give 2-fluoro-N-acyl-N-mesylanilines 4b-8b, which function as good chemoselective N-acylation reagents, especially for benzyloxycarbonylation. [References: 21]
