PROCESS FOR OBTAINING 1, 2, 3, 5, 6, 7, 8, 8A-OCTAHIDRO-1, 2, 8, 8 TETRAMETILNAFTALEN-2-IL-ETAN-1-ONA. |
| abstract |
A process for obtaining ketone of the formula (1a, b), which includes contacting a ketone represented by the formula (2a, b) with a first catalyst under certain conditions and for a time sufficient to obtain an intermediate mixture, whose mixture intermediate contains a ketone represented by the formula (4a, b) and contacting the intermediate mixture, or a fraction thereof, with a second catalyst under effective conditions to provide a product containing a ketone of the formula (1a, b ). In addition, the first catalyst preferably differs from the second catalyst with the first catalyst being preferably an isomerization catalyst and the second catalyst being a cyclisation catalyst. The process is capable of unexpectedly providing increased yields of ketone 4 and ketone 1. |
