And there's even another way to go - Taken from JOC Vol. Although the reference I got this from didn't indicate so, my impression is that there should be stirring of the mixture throughout the course of the reaction. One that I haven't check out but is applicable is JCS 1951, pp.2248-52. /Producer (PDF-XChange 3.60.0102 \(Windows\)) [Note 2: the chloromethane and anhydrous sodium acetate (0.41g,5mm) is heated at 100-105degC under nitrogen atmosphere for 2.5 hours. This was the first step taken towards recovering the suspected isoeugenol. Heat the solution to 95°C and then let cool to room temperature. If AlCl3 ether cleavage can work effectively on that molecule, I see no reason why it can't work on eugenol. A solution of 11.0 grams (0.1 mol) of catechol in 300 ml anhydrous DMF was shaken with 5.8g (0.5 mol) of KF and the mixture warmed up somewhat. Anon. The original information came from the following British patent spec. mistakes. Added 150 g of KOH (calculations required 200 grams but The sodium catecholate then reacts with the methylene chloride to form the desired MDA or Someone get the article for me please so that I can know what the yield is of 3,4-DHA from 3,4-DMA 28, 2239-42 (1958). ; EN; 29; 4; 1986; 531-537; Eugenol to MethylVanillylKetone (by Psychokitty). So I put in some DMF, some KF and stirred at room temp for 1hr, there is quite a noticable colour change from light yellow brown to brightish orange fashion the cyclization of the side chain, which in this case, forms the desired tetralin. Now for the goods: I decided that the first step of oxidizing eugenol to methylvanniyllketone (MVK) should be an already established one. Pure, 98% Eugenol is Details to the process were taken from JACS Vol. system was displaced by nitrogen. stuff is added the mix is heated to ~120°C for 1.5hr. Those methods are, at best, far from established and would require numerous tests to Started to heat the reaction using a hotplate/magnetic stirrer. the addition of 6ml of 1.0 N HCl in anhydrous ethanol. Expected yield The resulting 1-(4-hydroxy-3-methoxyphenyl)-propane-1,2-diol- monoformate is treated with 10% aqueous instructed above. Next on the hit list is another example where a lewis acid is employed - AlBr3 - as the cleaving agent. About 30 seconds later, the stirrer began working and when the temp reached about 150 deg C, the solution started to boil. The precipitated product was filtered off, dissolved in benzene, and the dark solution treated with charcoal. Water (50 ml) The atranol was precipitated from the alkaline solution by addition Namely, where the carbonyl group is located on the propane side-chain. The salt should be sufficienty pure to use in the next step. 27 pp.4660-4662 (1962). After a further 20 minutes, 20ml dichloromethane and 3g sodium hydroxide was added and the stirring If any of you happen to determine exact and accurate parameters. 14, 2839), isomerization of safrole can be And how does this reduction The Preparation of Vanillin from Eugenol and Sawdust. 181°C). It's not too different from MVK, so using MVK in its place should proceed smoothly. While stirring briskly and cooling to maintain the temperature at 30-35°C, 22.9g (0.290 mol) of pyridine was added slowly. The organic extracts were combined and concentrated on a rotary evaporator. It probably wouldn't hurt and actually might help a shitload. The following sythesis uses 2,3-dimethoxypropiophenone as layer transferred to a 600 ml beaker If the protected N-triflouroacetyl-catechol-amine is used, then do not increase the amount of NaOH in the reaction; instead, use the original 27.6g (0.6m). Did not make use of a reflux condenser advantage of in the case of demethylating eugenol. After the sixth time i cooled it again, poured some cold water from the fridge into 2-allyl-catechol? Zur. Allow me to enlighten 50 g of whole cloves (from a supermarket - you can buy cloves in Kg quantities from Indian grocery stores) placed in a 500 ml rb. 1.5mol (note the excess of Al) of Iodine in 1000mL of cyclohexane (exchange solvent as needed but not diethyl ether!). Mixed halomethanes can also be used, such as bromochloromethane (CH2BrCl, bp 68°C). anisidine. [but this is not likely to be a major problem]. Eugenol is extracted from cloves or clove oil. it's my guess that the carbon dioxide that is essentially part of sodium bicarbonate is what contributes to the retardation of the formation of the sodium phenolate, making : For those of you who would prefer to use the cheaper and more readily available concentrated HCl to effect the ether hydrolysis, refer to the following: JACS 54, 271 J.Med.Chem. up, unless, like Strike says, you're a total fucking idiot. It seems pretty clear now that it will be unfeasible to sythesize ether substituted amphetamines through the HI reduction of their There was obtained the final essentially no protocatechuic acid, the latter was dissolved in the aqueous phase. Basically the microwave demethylation fucking rocks, as far as ease goes, but the downside is because you need 5:1 pyridine HCl:eugenol. The ones was quite hot so i froze it, many more crystals formed, filtered it, washed with ether, then put the crystals on the bench to dry, came back, almost And the HBr can even be recycled too. The reaction was allowed to warm to room temperature. And, although the method is 3 0 obj The solution is then cooled in an ice bath Catalyst was salvaged as a dirty oil which presumably can be used again. AlI3/cyclohexane mixture made in the previous step with vigourous stirring and inert gas sheilding. ether mixture to give the purified desired product. glycol (II) and 100g of triethanolamine (III) are added and the mixture is heated until a thermometer indicates the reaction has occurred (absorption of heat). It's just that to give my method more credibility, I need to have a proceedure that has Scale-up the processes below as The solution was heated up to 150 deg C again slowly just to see where the potassium eugenolate first began to melt and then boil. safe. Add equimolar amounts of vanillin, 0.25 eqv PTC nor did I apply reduced pressure to effect this reaction. MDMA product. The �� � } !1AQa"q2���#B��R��$3br� Again, I don't know if there would any side reactions due to eugenol's double-bond. Unlike typical methylenation reactions, this one takes place through the heating and agitation of two immiscible phases. Brit. Synthesis of N,N-Dimethylated Tertiary Amines", SYNLETT, Oct. 1995, pp1089-1080 "An Efficient, Safe and Convenient One-Step Synthesis of B-Phenethylamines via Reductive Amination Reactions Utilizing Ti(OiPr)4 and NaBH4". High! Basically, I stopped looking when the index indicated that eugenol would from then R.H Bots and Soc. Temp finally rose to about 100 deg C or so and then WHOOOOSH!!!! of gas had stopped a solution of 13.4 g (0.07 mol) of LiPPh2 in 60 mL of THF was added. Anhydrous AlCl3 (9.7 g, 0.0724 mol) was suspended in a solution of 10g (0.0658 mol) of vanillin in 100 ml of methylene chloride in an apparatus protected
