The following report describes novel methodology for the rapid synthesis of unique conformationally constrained norstatine analogs of potential biological relevance. A PADAM (Passerini reaction–Amine Deprotection–Acyl Migration reaction) sequence is followed by a TFA-mediated microwave-assisted cyclization to generate the final benzimidazole isostere of the norstatine scaffold in moderate to good yields

A diastereoselective intramolecular Pictet–Spengler condensation was developed to achieve an SP3-rich 6-5-6-6 ketopiperazine-type scaffold. The cyclisation employs tryptophan-based dipeptide precursors which allow product stereochemistry to be tailored using readily available d and l amino acids. SAR analysis, examining different scaffold substitutions and stereochemical configurations, led to the
