Synthetic Studies on Enantioselective Total Synthesis of Cyathane Diterpenoids: Cyrneines A and B, Glaucopine C, and (+)-Allocyathin B2

The details for the synthetic studies on enantioselective total synthesis of cyathane diterpenoids cyrneine A (1) and B (2), glaucopine C (3), and (+)-allocyathin B2 are presented. We established a mild Suzuki coupling for heavily substituted n

Total synthesis of (+)-allocyathin B2

The first enantioselective synthesis of (+)-allocyathin was achieved. The synthesis features a Pd-catalyzed asymmetric allylic alkylation to install the first quaternary center, a Ru-catalyzed diastereoselective cycloisomerization to construct the six-mem
