Application of the chemo- and enantioselective cyclopropanation of polyenes to the total synthesis of (+)-bicyclohumulenone

The chemo- and enantioselective cyclopropanation of a monoprotected bis(allylic alcohol) using a chiral dioxaborolane- derived ligand and Zn(CH2I)2 was used as a key step in the total synthesis of (+)-bicyclohumulenone. The synthesis
