, p. 5161 - 5164 (1990)
The copper (I) catalysed substitution of allylic chlorides by alk-1-ynes leads to the synthesis of new terpene derivatives. An efficient synthesis of phytone is described.

Three novel polyprenols, named glycinoprenol-9, -10, and -11, in addition to ficaprenols were isolated from the leaves of soybean, Glycine max Merill.The glycinoprenols were found to possess a phytyl residue, four to six internal (Z)-prenyl residues, and a Z α-terminal residue aligned in that order on the basis of their IR, 1H NMR, 13C NMR, and mass spectral data.The configurations of two chiral centers in the phytyl residue were determined to be all R by a combination of chemical and spectroscopic methods.
SYNTHESIS OF NEW UNSATURATED ESTERS, CATALYZED BY PALLADIUM-PHOSPHINE COMPLEXES
Mignani, G.,Grass, F.,Aufrand, M.,Morel, D.
, p. 2383 - 2386 (1989)
The palladium-catalyzed addition of allylic chlorides to carbonucleophiles leads to the formation of new terpene derivatives.A facile and economical route of phytone is described.
An Efficient Alternative to the Total Synthesis of Isophytol
Yerramreddy, Thirupathi R.,Yiannikouris, Alexandros
, p. 996 - 999 (2022/02/17)
An improved and alternative method for the total synthesis of isophytol from citral via using pseudoionone intermediate was developed and described in this manuscript. This alternative commercially viable approach involves six steps and it represents an alternative method commercially viable over existing published synthetic methods in the literature. This goal was achieved by developing and optimizing an efficient and high yield procedure for the synthesis of a key intermediate i.e. 6,10,14-trimethylpentadectrimethylpentadec-5-en-2-one, by reacting 2-methoxypro-pene with a tertiary alcohol (3,7,11-trimethyldodec-1-ene-3-ol). Isophytol was provided in 58-60% overall yield from citral with >99% purity, evaluated by TLC, GC, and NMR.

Paragraph 0061; 0084-0085, (2020/07/21)
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)
