Starchman, Evangeline S. published the artcileSynthesis of (±)-rupestines B and C by intramolecular Mizoroki-Heck cyclization, Related Products of esters-buliding-blocks, the publication is Tetrahedron Letters (2020), 61(19), 151837, database is CAplus.
The total synthesis of rupestines B and C, I (R = α-Me, β-Me, resp.), two guaipyridine sesquiterpene alkaloids, is reported. These compounds are isolated from Artemisia rupestris L. and have structural similarities to that of cananodine, a guaipyridine alkaloid with activity against two liver cancer cell lines. The synthesis of rupestines B and C was accomplished in six steps using an intramol. Mizoroki-Heck cyclization as the key-step to form the seven-membered carbocycle of the targets.
