Hybrid Calix[4]arenes via Ionic Hydrogenation and Transition-Metal-Mediated Processes
摘要:
We report the first application of ionic hydrogenation for the synthesis of upper-rim urea- or carbamate-derived hybrid calix[4]arenes. Subsequent metal-mediated transformations using 4-iodophenylurea calixarenes afforded structurally unique 1,3-di(biaryl)-, 1,3-di(biarylalkyne)-, or 1,3(biaryl)(biarylalkyne)-derived hybrid calixarenes.
