One-Pot Synthesis of 5,6-Dihydro-4H-1,2-Oxazines by Cyclization of Ketoximes with Derivatives of Allylbenzene [PDF]

open access: yesJOURNAL OF ADVANCES IN CHEMISTRY, 2010
A new series of 5,6-dihydro-4H-1,2-oxazines were synthesized via hetero Diels-Alder reaction of  α-nitrosolefins with derivatives of allylbenzene. α-Nitrosoolefins were generated from ketoximes by the action of chloramine-T and triethylamine.

Mechanochemical Piezoelectric Catalysis: Advancing the Hydrogenation of Alkenes. [PDF]

open access: yesAdv Sci (Weinh)
This study presents mechanochemical piezoelectric catalysis for alkene hydrogenation, eliminating the need for transition metals, H2, and solvents. The method effectively hydrogenates diverse activated and unactivated alkenes and shows potential for modifying bioactive molecules in pharmaceuticals.

Solubilized Formulations of Triphenylphosphine Derivatives of Allylbenzenes and Their Potential as Individual Antitumor Agents or Adjuvants to Paclitaxel

open access: yes, 2023
Allylbenzenes (apiol, dillapiol, myristicin and allyltetramethoxybenzene) are individual components of plant essential oils that demonstrate antitumor activity, as well as enhancing effect on cytotoxic drugs such as paclitaxel, doxorubicin, cisplatin, etc.

Wagner-Meerwien rearrangement of allylbenzene derivatives. I. Bromination of safrole.

open access: yesChemical and Pharmaceutical Bulletin, 1975
The reaction of safrole (I) with bromine (II) was examined giving different results from the literature, i.e., 2, 3-dibromo-1-(3', 4'-methylenedioxyphenyl) propane (III), 1, 3-dibromo-2-(3', 4'-methylenedioxyphenyl) propane (V) and their bromo-substituted derivatives (IV and VI) were obtained.

Contra-Thermodynamic Chain-Walking Isomerization: A Sustainable Tool for Selective Molecular Editing in Green Chemistry. [PDF]

open access: yesChemSusChem
Contra‐thermodynamic chain‐walking isomerization enables selective migration of alkenes to less stable yet synthetically valuable terminal position under mild, catalytic conditions. By integrating tailored metal catalysis, photochemical, and redox strategies, this approach affords efficient access to terminal and remote functionalized products with ...

Di-π-Methan-Umlagerungen von methylsubstituierten Allylbenzolen

open access: yesCHIMIA, 1981
Allylbenzene (3) and its derivatives bearing methyl groups at the aromatic ring or at C(1') of the allyl chain (see scheme 1-3, and 6) can cleanly be transformed into the corresponding cyclopropylbenzenes via a triplet di-π-methane rearrangement when ...

Characterization of Odorous and Potentially Harmful Substances in Artists' Acrylic Paint

open access: yesFrontiers in Public Health, 2018
Acrylic paints are fast drying water based paints that are easy to handle and have a high covering capacity and therefore possess many characteristics that make them applicable in a wide range of applications, such as varnishes or artists paints.
