A new tetrafluorophenol activated resin that facilitates the use of F-19 NM
R to quantitate loading is presented. This new resin provides a useful tool
for acylation, and a novel activated polymeric sulfonate ester to generate
sulfonamides. This activated resin reacts with a wide scope of N-nucleophi
les including primary and secondary amines, and anilines. This new activate
d resin methodology provides a powerful tool for pure single-compound libra
ry synthesis.
