Formal synthesis of (-)-α- and (+)-β-Cuparenones, Cuparene, and Laurene

This paper describes formal synthesis of the title compounds from easily prepared chiral synthon (+)-5.One of the structural features of the cuparene family is the presence of vicinal quaternary carbons on the five-membered ring.The quaternary carbon with
