Terpenoids to terpenoids: Enantioselective construction of 5,6-, 5,7-, and 5,8-fused bicyclic systems. Application to the total synthesis of isodaucane sesquiterpenes and dolastane diterpenes

The prevalence of a C12 common core (10) in C15-C30 terpenoids has been recognized. Construction of two "chirons" ((-)-11 and (-)-12a,b), corresponding to 10, from abundantly available (R)-(+)-limonene has been achieved th
