- Total synthesis of (±)chokol-A via an intramolecular type-I-magnesium ene reaction
Oppolzer, W.; Cunningham, A. F.
Tetrahedron Lett. 1986, 27, 5467-5470
The sesquiterpene (±)chokol-A (1) was synthesized in a diastereoselective manner starting from 1-hexen-5-one-trisylhydrazone (5). The key step 7→8 involves the regio- and stereo-selective magnesium-ene reaction 4→3.
