Rhodium‐Catalyzed Cyclization of Terminal and Internal Allenols: An Atom Economic and Highly Stereoselective Access Towards Tetrahydropyrans

A comprehensive study of a diastereoselective Rh‐catalyzed cyclization of terminal and internal allenols is reported. The methodology allows the atom economic and highly syn‐selective access to synthetically important 2,4‐disubstituted and 2,4,6‐trisubstituted tetrahydropyrans (THP). Furthermore, it...

Sumario:A comprehensive study of a diastereoselective Rh‐catalyzed cyclization of terminal and internal allenols is reported. The methodology allows the atom economic and highly syn‐selective access to synthetically important 2,4‐disubstituted and 2,4,6‐trisubstituted tetrahydropyrans (THP). Furthermore, its utility and versatility are demonstrated by a great functional‐group compatibility and the enantioselective total synthesis of (−)‐centrolobine.
