Abstract: We report here an effective protocol to prepare highly functionalized dihydropyrans via sequential reaction of cross-coupling-intramolecular Michael addition of functionalized terminal alkynes and diazo compounds under mild reaction conditions. Importantly, by choosing different ligands, the… read more here.
