A uncomplicated synthesis of a really substituted biomass-derived chiral pyrrolidine conveniently functionalized to get macrocycles as a result of intramolecular “click” reactions is claimed. The experimental troubles encountered through the macrocyclization stage led us to conduct an in depth DFT study to comprehend the origins of the findings. The results acquired propose that the improper conformational landscape of the reactant precludes the pre-corporation required to link the reactive moieties. We suggest that the cumulative Boltzmann amplitudes of reactive conformations (CBAR) verify to be a basic and handy parameter to forecast the achievements or failure of linked transformations.
