This invention relates to novel 1,4- and 1,5-diarylsubstituted 1,2,3-triazole derivatives that are found to be potent modulators of potassium channels and, as such, they are valuable candidates for the treatment of diseases or disorders as diverse as those which are responsive to modulation of potassium channels.

A tandem rearrangement of alpha,beta-unsaturated, thioesters into tricyclic ene-lactones fails with conventional amidine-based catalysts, but becomes possible when their electron-rich analogs are employed. A highly diastereo- and enantioselective version of this process has been developed using H-PIP 1b, a chiral catalyst prepared over a decade ago, but never utilized since its disclosure.
