Atom-Economical Chemoselective Synthesis of 1,4-Diynes and Polysubstituted Furans/Pyrroles from Propargyl Alcohols and Terminal Alkynes

Under different conditions, the reaction of propargyl alcohols and terminal alkynes leads to the selective formation of 1,4-diynes and polysubstituted furans/pyrroles. Water is the only byproduct in the selective synthesis of 1,4-diynes and pyrroles, and the strategy for the furan synthesis is of 100% atom economy.
