Abstract

A series of phenyl 2-aminopyridine-3-sulfonates 3 has been synthesized starting from phenyl cyanomethanesulfonate (5). Pinner reaction with 5 gave phenoxysulfonylketene aminal 4K which was cyclocondensed with a series of C3-biselectrophiles to yield the title compounds, which are of pharmaceutical and medicinal interest.

Key words

pyridines - condensation - tautomerisation - phenoxysulfonylketene aminals - 2-aminopyridine-3-sulfonates
