Gold(I)-Catalyzed Domino Reaction for Furopyrans Synthesis [PDF]

open access: yesMolecules, 2020
We report herein an efficient synthesis of furopyran derivatives through a gold(I)-catalyzed domino reaction. The cascade reaction starts with two regioselective cyclizations, a 5-endo-dig and a 8-endo-dig, followed with a Grob-type fragmentation and a ...
