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.
Method for preparing allyl alcohol compound by reduction of propargyl alcohol compound
-
Paragraph 0063-0064, (2021/11/10)
A hydrazide compound is used as a reducing agent, an organic amine is used as an auxiliary, and the propargyl alcohol compound is selectively reduced to obtain an allyl alcohol compound under the presence of a solvent and a certain temperature. The method does not need Pd catalyst which is expensive, and the reducing agent and auxiliary agent are cheap and easily available, easy to separate, free of residue in the product, simple in reaction operation process, mild in reaction condition, high in target product selectivity and the like.
SELECTIVE HYDROGENATION OF ALKYNOLS TO ALKENOLS IN THE PRESENCE OF A PHOSPHORUS COMPOUND
-
Page/Page column 16-17, (2020/12/11)
The present invention relates to a process of hydrogenating an aIkynoI selectively to an alkenol by hydrogen using a hydrogenation catalyst which is palladium supported on a carrier in the presence of an additive which is an organic phosphorus compound bearing either a phosphine or a phosphine oxide group and with the proviso that if the additive bears a phosphino group that the additive bears two or more phosphino groups.
