The monolignol pathway contributes to the biosynthesis of volatile phenylpropenes in flowers

New Phytologist, 2014
Summary Volatile phenylpropenes play important roles in the mediation of interactions between plants and their biotic environments. Their biosynthesis involves the elimination of the oxygen functionality at the side‐chain of monolignols and competes with lignin formation for monolignol utilization.

2,4-Dinitrobenzenesulphenylnitrene: addition to (Z)- and (E)-1-phenylpropene

Journal of the Chemical Society, Perkin Transactions 1, 1982
Oxidation of 2,4-dinitrobenzenesulphenamide (1) with lead tetra-acetate in the presence of (Z)-1-phenylpropene gives a ca. 3:1 mixture of cis- and trans-aziridines (3) and (4), respectively. This ratio is unchanged over a tenfold decrease in concentration of (Z)-1-phenylpropene.

Cobalt, nickel, and copper coordination compounds with 3-phenylpropenal benzoylhydrazone

Russian Journal of General Chemistry, 2006
3-Phenylpropenal benzoylhydrazone (HL) reacts with cobalt, nickel, and copper chlorides, nitrates, and acetates to give coordination compounds MX2 · nH2O [M = Co, Ni, Cu; X = Cl, NO3, HL = C6H5CH=CHCH=NNHC(O)C6H5; n = 0, 2] and ML2 · nH2O (M = Co, Ni, Cu; n = 1–3).

Bioherbicidal activity of terpenes and phenylpropenes against Echinochloa crus-galli

Journal of Environmental Science and Health, Part B, 2019
This study was undertaken to evaluate the herbicidal activity of twelve natural compounds belonging to monoterpenes, phenylpropenes, and sesquiterpenes against Echinochloa crus-galli under laboratory and glasshouse conditions. Experiments were conducted to determine the impact of different concentrations (0.5, 1, 2, 4 and 8 mM) of these compounds on ...

Enantioselectivity in the Rabbit Liver Microsomal Biotransformation of Styrene and Phenylpropenes

Biocatalysis, 1994
The rabbit liver microsomal P-450 catalyzed oxidation of styrene (1a) and isomeric phenylpropenes, trans-1-phenylpropene (1b), cis-1-phenylpropene (1c) and 3-phenylpropene (1d), was investigated and the enantioselectivity of the epoxidation of the olefinic double bond was determined by checking the enantiomeric excesses of the corresponding first ...

1-(2-hydroxy-3,4,5,6-tetramethoxyphenyl)-3-phenylpropene from Lindera lucida

Phytochemistry, 1998
Abstract A new diarylpropene, 1-(2-hydroxy-3,4,5,6-tetramethoxyphenyl)-3-phenylpropene, has been isolated from twigs of Lindera lucida. Its structure was determined by spectral analysis and chemical correlation.

ChemInform Abstract: Oxidative Photoaddition of N‐Nitrosodimethylamine to 1‐Phenylpropenes.

ChemInform, 1987
AbstractIn the presence of HCl and under oxygen purging, the nitrosamine (V) photolytically adds to the arylpropenes (Ia), (Ic) to give threo‐ and erythro‐α‐amino nitrates (III) or (VIII) as the primary products which are reduced to yield the α‐amino alcohols (IV) or (IX), respectively.

Oxidative photoaddition of N‐nitrosodimethylamine to 1‐phenylpropenes

Recueil des Travaux Chimiques des Pays-Bas, 1986
AbstractIn the presence of hydrochloric acid and under oxygen purging, N‐nitrosodimethylamine photolytically adds to 1‐arylpropenes regiospecifically to give erythro‐ and threo‐α‐amino nitrates as the primary products which can then be reduced, using lithium aluminium hydride, to give α‐amino alcohols or can undergo substitution reactions under ...

Alkylation of p-cresol with 3-phenylpropen-1-ol-3

Bulletin of the Academy of Sciences, USSR Division of Chemical Science, 1964
1. The alkenylation of p-cresol with phenacyl alcohol in the presence of zinc chloride on aluminum oxide goes in the direction of the formation of 1-phenyl-3-(3-methyl-6-hydroxphenyl)propene-1 in 80% of theoretical yield. 2. The alkenylation of p-cresol with phenacyl alcohol proceeds with a larger yield than the allylation of p-cresol ...
