in situ from t-BuOCl and NaI. A variety of 2,5-disubstituted1,3,4-oxadiazoles were synthesized in high yields within short reaction time. The method is also suitable for cyclization of N-acylhydrazones derived from heterocyclic aldehydes and aliphatic aldehydes. Mild reaction conditions and simple workup operations make the procedure a good alternative for the synthesis of 2,5-disubstituted 1,3,4-oxadiazoles

so far. We describe a novel platform by which an inhibitor was selected out of around 185 compounds directly from reaction media containing thiosemicarbazones and mono-, di-, and trihydrazones. To achieve this, tandem library preparation, thin-layer chromatography (TLC) bioautography, and effect-directed deconvolution were applied. We illustrate the potential of this effect-directed synthesis for the
