N-Tert-butyloxycarbonyl groups can be removed from substrates supported on Rink's amide resin by treatment with trimethylsilyl triflate/2,6-lutidine. This methodology was illustrated here with syntheses of several peptides, but it is likely to be used more extensively in solid phase syntheses of small molecule libraries.

purification/structural analysis approach. The traditional approach resulted in the identification of the known inhibitor antipain (1) and its new but lower potency dehydration product 2, while the affinity crystallography approach led to the identification of a newhigh-affinityinhibitor named lichostatinal (3). The structure and potency of lichostatinal (3) was verified by total synthesis and kinetic characterization
