In the present study, we compared the antiepileptic effects of α-asarone derivatives to explore their structure-activity relationships using the PTZ-induced seizure model. Our research revealed that electron-donating methoxy groups in the 3,4,5-position on phenyl ring increased antiepileptic potency but the placement of other groups at different positions decreased activity. Besides, in allyl moiety, the optimal activity was reached with either an allyl or a 1-butenyl group in conjugation with the benzene ring. The compounds 5 and 19 exerted better neuroprotective effects against epilepsy in vitro (cell) and in vivo (mouse) models. This study provides valuable data for further exploration and application of these compounds as potential anti-seizure medicines.

Synthetic application of arynes is broadened by their reactions with neutral N-, S-, and O-containing nucleophiles to produce three types of compounds. Accordingly, 1,2-dihydroquinolines are synthesized from Schiff bases, alkynes, and arynes through a Diels-Alder reaction. Epoxides are prepared from thioethers and arynes along with aldehydes or ketones through a Johnson-Corey-Chaykovsky reaction. Phenolic ethers are produced from allyl ethers and arynes through a Claisen-type rearrangement. These target molecules, including natural products γ-asarone, asaricin, and a cholesteryl phenolic ether, are formed through reactions initiated by arynes. These new reactions share a prevailing feature of domino processes, which are carried out in a single flask and afford the desired products in good to high yields.

This work demonstrates an alternative method to prepare allylated arenes and aryl-substituted allylic esters via catalytic decarboxylative C-C bond formation using aromatic carboxylic acids and allylic halides and esters.

(Chemical Equation Presented) Tetrahydrofur-2-ylmethyl radicals were stereoselectively generated from substituted pent-4-en-1-ols in aerobic cobalt(II)-catalyzed oxidations. Intermediates were trapped with cyclohexa -1,4-diene, γ-terpinene, BrCCl3, diethyl dibromomalonate, or electron-deficient olefins such as acrylonitrile or dimethyl fumarate to afford functionalized tetrahydrofurans in synthetically useful yields.
A mild and convenient procedure for the conversion of toxic β-asarone into rare phenylpropanoids: 2,4,5-Trimethoxycinnamaldehyde and γ-asarone

Oxidation of β-asarone (2) with DDQ gave trans-2,4,5- trimethoxycinnamaldehyde (3), which on treatment with p-toluenesulfonyl hydrazine provided corresponding α,β-unsaturated hydrazone derivative (4). Reduction of 4 with sodium borohydride in acetic acid afforded γ-asarone (1) in 43% yield.

, p. 4119 - 4124 (2007/10/02)
Twenty-seven commercial or synthetic phenylpropanoids have been tested in broth against the unicellular alga Selenastrum capricornutum.The antialgal activity seems to be linked to the number as well as to the position of the methoxyl group in the molecule.A slight effect of the side chain substitution was also observed. Key Word Index - Selenastrum capricornutum; allelochemicals; phenylpropanoids.
ANODIC 1,2- AND 1,4-ADDITION PRODUCTS FROM METHYL EUGENOL AS PREDICTED BY THE EECrCp MECHANISM
Wang, Shaopeng,Swenton, John S.
, p. 1513 - 1516 (2007/10/02)
Anodic oxidation of 1,2-dimethoxy-4-allylbenzene (methyl eugenol) under a variety of constant current conditions in methanolic sodium hydroxide affords the 1,2- and 1,4-methanol addition products expected from the EECrCp mechanism.These results differ markedly from those recently reported.

γ-Asarone is synthesised in high yield, and conveniently, by anodic methoxylation of methyl eugenol, at constant current.The method is extremely simple and inexpensive.
IRON-MEDIATED AROMATIC ALLYLATION

, p. 5415 - 5418 (2007/10/02)
Electron rich aromatic and heteroaromatic compounds react with (η3-allyl)Fe(CO)4BF4 to produce allylated aromatics in moderate to good yields.Unsymmetrically substituted allyl complexes afford the corresponding butenyl-, 1,1-dimethylallyl-, cinnamyl-, and geranyl-derivatives with moderate to excellent regioselectivity and complete stereoselectivity.
