Asymmetric total synthesis of (R)-α-cuparenone, (S)-cuparene and formal synthesis of (R)-β-cuparenone through Meinwald rearrangement and ring closing metathesis (RCM) reaction

Asymmetric synthesis of enantiopure cuparenoid sesquiterpenes (R)-α-cuparenone, (S)-cuparene and a formal synthesis of (R)-β-cuparenone was presented in this article. Meinwald rearrangement of an enantiopure trisubstituted 2,3-epoxy alcohol derivative was

ENANTIOCONTROLLED SYNTHESES OF THE CUPARENE SESQUITERPENES, (-)-HERBERTENE, (+)-β-CUPARENONE, (-)-DEBROMOAPLYSIN, AND (-)-APLYSIN

Enantiocontrolled syntheses of the Cuparene sesquiterpenes, (-)-herbertene, (+)-cuparenone, (-)-debromoaplysin, and (-)-aplysin, have been achieved starting from the optically active tricyclic dienone by employing a Fischer indolization reaction under non-acidic conditions as the key step.

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
