New methods for the preparation of theaspiranes, megastigmane-5,7,9-trien-4-one and megastigmane-5,8-dien-4-one from γ-pyronene

γ-Pyronene, a terpenic synthon easily available from myrcene, an industrial raw material, is used as an intermediate in the synthesis of theaspiranes and various megastigmane derivatives. These compounds are useful in the preparation of perfumes and aromas. (C) 2000 Elsevier Science Ltd.

Isolation and synthesis of 3-(2-butenyl)-2,4,4-trimethyl-2-cyclohexen-1-one. Regiospecific oxidation of 1-(2-butenyl)-2,6,6-trimethylcyclohexene

(E)- and (Z)-3-(2-butenyl)-2,4,4-trimethyl-2-cyclohexen-1-one 1 and 2 have been isolated from an absolue of Osmanthus Fragrance Lour, and a fusel oil concentrate.Structural proof for these compounds has been obtained via their synthesis from β-ionone.The key step in this synthesis is the regio-specific oxidation of 1-(2-butenyl)-2,6,6-trimethylcyclohexene.
