ABSTRACT:
Described are hexahydrotetramethyl acetonaphthones and mixtures of such substituted acetonaphthones having the generic formula: ##STR1## wherein one of the dashed lines is a carbon-carbon double bond and each of the other of the dashed lines is a carbon-carbon single bond, and, specifically, the novel isomer having the structure: ##STR2## and processes for the preparation of such mixtures and said novel isomer, as well as a known single component of said mixtures and compounds, by means of first forming 3-chloromesityl oxide from mesityl oxide and chlorine and then reacting the 3-chloromesityl oxide with myrcene via a Diels-Alder reaction thereby producing a chlorine containing Diels-Alder adduct and then either:
