Total synthesis of (±)-parvifoline and (±)-isoparvifolinone
摘要:
The total synthesis of the unusual trimethylbenzocyclooctenes (+/-)-parvifoline (1) and (+/-)-isoparvifolinone (5) have been achieved by using the Grob fragmentation reaction of mesylate 25 as the key step.

An efficient enantioselective protocol has been reported to build highly oxygenated and densely substituted bicyclo[m.n.1] skeletons through intramolecular asymmetric α-arylative desymmetrization of 1,3-diketones. Employing Pd catalyst and FOXAP ligand, various bicyclo[m.n.1] skeleton with different size can be accessed with high enantio- and diastereoselectivities. Utilizing the present method as

A total synthesis of the sesquiterpene (+/-)-parvifoline 1 from the symmetrical naphthalene 4 is reported. The key step of the synthesis was a Stork-Landesman two-carbon ring expansion of beta-tetralone 5, which affords 9a with the complete framework of the target. Although many reactions are involved in the sequence, the whole synthesis can be executed in only five synthetic operations and in approximate to 18% overall yield.
