A LINEAR DITERPENE DIOL FROM LEMNA MINOR
Previtera, Lucio,Monaco, Pietro
, p. 194 - 195 (1984)
Four known isoprenoids were isolated from Lemna minor besides a novel diterpene which was attributed the structure (4R)-4-hydroxyisophytol by spectroscopic studies and chemical correlation.Key Word Index - Lemna minor; Lemnaceae; isoprenoids; 4-hydroxyisophytol.

Paragraph 0042-0050; 0082-0097, (2021/03/24)
The invention provides a method for efficiently preparing enol through selective hydrogenation of alkynol. A conventional tank reactor and a micro-channel reactor are combined for use, and the micro-channel reactor can be used for quickly preparing an enol product after immobilizing a rare earth metal doped catalyst, so that the reaction time is shortened, and the production efficiency is improved. And a phosphine compound is added as a side reaction inhibitor to improve the selectivity.
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)
