|Title:||Enantiospecific synthesis of sesquiterpenes from (R)-carvone. Synthesis of 3-thapsenol|
|IPC Code:||Int.Cl.7 C 07 13/08|
|Abstract:||Enantiospecific synthesis of 3-thapsenol, comprising the carbon framework of a small group of sesquiterpenes containing three contiguous quaternary carbon atoms has been described. (R)-Carvone has been employed as the chiral starting material utilizing the isopropenyl group as a masked hydroxy group. A combination of alkylation, orthoester Claisen rearrangement and intramolecular diazo ketone cyclopropanation reactions has been employed for the creation of the three requisite contiguous quaternary carbon atoms.|
