The present invention is directed to novel methods for production of 5-epi-β-vetivone, 2-isopropyl-6,10-dimethyl-spiro[4.5]deca-2,6-dien-8-one and 2-isopropyl-6,10-dimethyl-spiro[4.5]deca-1,6-dien-8-one, which are useful for their fragrant qualities. In one embodiment the present invention describes a method for production of 5-epi-β-vetivone by the use of premnaspirodiene as starting material. In another embodiment the present invention describes a method for production of 2-isopropyl-6,10-dimethyl-spiro[4.5]deca-2,6-dien-8-one and 2-isopropyl-6,10-dimethyl-spiro[4.5]deca-1,6-dien-8-one by the use of premnaspirodiene as starting material. In yet another embodiment the present invention describes a novel method for production of premnaspirodiene from a terpene substrate.
本发明涉及生产5-epi-β-vetivone、2-异丙基-6,10-二甲基-螺[4.5]癸-2,6-二烯-8-酮和2-异丙基-6,10-二甲基-螺[4.5]癸-1,6-二烯-8-酮的新方法,这些化合物因其芳香特性而有用。在一种实施方式中,本发明描述了一种使用premnaspirodiene作为起始物质生产5-epi-β-vetivone的方法。在另一种实施方式中,本发明描述了一种使用premnaspirodiene作为起始物质生产2-异丙基-6,10-二甲基-螺[4.5]癸-2,6-二烯-8-酮和2-异丙基-6,10-二甲基-螺[4.5]癸-1,6-二烯-8-酮的方法。在另一种实施方式中,本发明描述了一种从萜类底物生产premnaspirodiene的新方法。
