A New Route to Substituted Phenols by Cationic Rhodium(I)/BINAP Complex-Catalyzed Decarboxylative [2 + 2 + 2] Cycloaddition
摘要:
A new route to substituted phenols has been developed by cationic rhodium(I)/BINAP complex-catalyzed decarboxylative [2 + 2 + 2] cycloadditions of 1,6- and 1,7-diynes with commercially available vinylene carbonate.

A novel Rh-catalyzed carbonylative [3 + 2 + 1] cycloaddition of alkyne-tethered alkylidenecyclopropanes for the facile synthesis of bicyclic phenols in high yields has been developed. The reaction tolerated carbon and heteroatoms in the tether.

The development of the rhodium-catalyzed [(3+2)+1] carbocyclization reaction of alkynylidenecyclopropanes with carbonmonoxide to construct polysubstituted phenols is described. This work offers a convenient method for the selective formation of tetra- and pentasubstituted phenols, which provide important intermediates for target directed synthesis. Finally, the ability to regiospecifically functionalize
