L-Allyl-4-methoxybenzene

The antibacterial compounds used in packaging materials are either synthetic or of namral origin and include (a) Organics allyl isothiocyanate, propionate, benzoate, sorbate, ethanol, linalool, methyl chavicol (l-allyl-4-methoxybenzene), dtral (3,7-dimethylocta-2,6-dienal ), methylcinnamate, methyleugenol, geraniol, 1,8-cineole, tra/is-a-bergamolene, carvacrol (5-isopropyl-2-methylphenol), thymol (2-isopropyl-5-methylphenol), l-octen-3-one, 3-octanol, ethyl pyruvate (ethyl... 

An equally important but similar example is estragol (l-Allyl-4-methoxybenzene) also known as methylchavicol. In 2000, the CEFS of the council of Europe evaluated estragol, and based on their ndings (it was found to be a naturally occurring genotoxic carcinogen in experimental animals), a limit of 0.05 mg/kg (detection limit) was recommended [12]. 

Regarding the chemical names, in the Commission Proposal no trivial name is given for l-allyl-4-methoxybenzene (estragol) and 4-allyl-l,2-dimethoxy-benzene (methyleugenol) in contrast to the Council Proposal (synonyms given). 

Allyl-l-(allyloxymethyl)-3-isopropoxy-4-methoxybenzene 149 can undergo a one-pot ruthenium catalyzed isomerization followed by RCM in the presence of Grubbs second generation catalyst 37 to afford 5-isopropoxy-6-methoxy-1 //-isochromcnc (Scheme 48) <2003SL1859>. 

Myristicin, l-allyl-3,4-methylenedioxy-5-methoxybenzene, a naturally occurring alkenylbenzene found in nutmeg, produced neurotoxic effects. Myristicin at > 0.5 mM concentration showed cytotoxicity in human neuroblastoma cells (Lee et al., 2005).

Foods may contain a number of alkyl aryl ethers that are components of essential oils of different spices as well as secondary substances. These ethers are most often derived from anisole (methoxybenzene, 8-33) or veratrole (1,2-dimethoxybenzene, 8-33), which are substituted by a prop-l-en-yl or l-prop-2-en-l-yl (allyl) group at the C-4 position of the benzene ring. An important ether is estragole (also known as 4-aUylanisole or methyl chavicol, 8-33), which is the main component (over 80%) of basil essential oil (see Table 8.32, later) and tarragon (dragon s wort) essential oil...
