Synthesis method and method for synthesizing plant alcohol, isoplant alcohol and geranyl geraniol by using intermediate farnesylacetone (by machine translation)

The invention relates to a synthesis method of intermediate farnesyl acetone and a method for synthesizing vitamin E, vitamin K1, vitamin K2 side chain isovegetable alcohol, plant alcohol and geranyl geraniol by using farnesyl acetone, and concretely relates to hydrogenation of 5 - farnesyl -2 - acetone and farnesyl acetone through three Grignard reaction to obtain plant ketone. The farnesyl acetone reacts with the vinyl chloride Grignard reagent to obtain geranyl linalool, the aromatic leaf-based geraniol is rearranged under acid catalysis, or farnesyl acetone is directly reacted with the hydroxyl-protected 2 - chloroethanol Grignard reagent to obtain geraniol. The plant alcohol is reacted with the vinyl chloride Grignard reagent to obtain the plant alcohol, and the plant alcohol is directly reacted with the hydroxyl-protected 2 - chloroethanol Grignard reagent to obtain the plant alcohol. The method has the advantages of cheap and easily available starting materials, short synthetic process steps, low product cost and the like. (by machine translation)

Novel intermediate for synthesizing teprenone and application of novel intermediate

The invention discloses a novel intermediate for synthesizing teprenone. The novel intermediate is a compound shown as a formula 5. The novel intermediate has the advantages that process routes for synthesizing the teprenone by the compound shown as the formula 5 are simple, raw materials are easily available, reaction conditions are mild, side reaction rarely can be carried out, and accordingly the novel intermediate is favorable for industrial production; the high-purity teprenone can be obtained by the aid of the process routes without rectification, and the requirements on ratios of isomermono-cis-form (5Z, 9E and 13E) to all-trans-forms (5E, 9E and 13E) of the teprenone can be met.
