New Preparation Methods for α‐Damascone, γ‐Damascone, and β‐Damascenone using Pyronenes

Abstract

γ‐ and δ‐Pyronenes are terpenic synthons easily available from myrcene. They are used as intermediates in the synthesis of α‐damascone, γ‐damascones, and β‐damascenone.

Keywords:

• α‐damascone
• β‐damascenone
• γ‐damascone
• pyronenes
• terpenes
• terpenoids
