Based on the reactive behavior of different transition-metal catalysts, three methods for the synthesis of highly functionalized polysubstituted furan derivatives are presented: (i) copper(I) iodide catalyzed regiospecific synthesis of furan aldehydes/ketones from alkynols and diethyl but-2-ynedioate under atmospheric pressure; (ii) nano-Cu2O-catalyzed domino process for the regioselective synthesis
Transition metal‐catalyzed domino reactions have been used as powerful tools for the preparation of polysubstituted furans in a one‐pot manner. In this paper, an efficient synthetic method was developed for the construction of tri‐ or tetrasubstituted furans from electron‐deficient alkynes and 2‐yn‐1‐ols by a silver‐catalyzed domino reaction. It is especially noteworthy that a 2,3,5‐trisubstituted
