Abstract: | The first enantioselective total synthesis of (-)-erinacine B has been achieved. Our approach features convergent construction of the 5-6-7 tricyclic cyathane core system via chiral building blocks prepared using asymmetric catalysis developed by us and highly stereoselective construction of all stereogenic centers in the aglycon. reaction: see text]. |
