90% With lithium chloride In <i>N</i>,<i>N</i>-dimethyl-aniline at 190℃; for 3 h; Inert atmosphere To a 500 ml 3 necked RBF equipped with an overhead stirrer, N2 inlet and a water condenser, were charged 5-allyl-3-methoxysalicylic acid (100 g, 0.48 mol., obtained above), N,N-dimethylaniline (20 ml, SRL 99.5percent pure) and anhydrous lithium chloride (0.750 g, 0.0176 mol., SRL 99percent pure). The above mixture was then heated gradually to 190 °C. The mixture begins to melt slowly as the bath temperature reaches 130 °C, becomes stirrable slurry at 150 °C and eventually a homogeneous liquid as the temperature approaches 190 °C. The reaction mixture was maintained at 190 °C for about 3h. Progress of the reaction was monitored by quenching aliquot sample with dilute hydrochloric acid followed by extraction with solvent (EDC or ether) and analyzing by HPLC (area percent) for the conversion of acid to eugenol. Having ensured the complete conversion of acid by HPLC, the reaction mixture was cooled to room temperature (25 °C) and diluted with 200 ml of 1,2- dichloroethane. To this dil. HC1 (28 ml of 35percent HC1 in 67 ml of water) was added such that the temperature of the reaction mixture does not shoot beyond 25 °C. The resultant mixture was then stirred for lh at room temperature followed by separation of the organic and aqueous layer. The resultant organic layer was passed through a bed of acidic sulphonated polystyrene resin cross linked with divinyl benzene (commonly known as Ion exchange resin, IER) to remove the residual N,N-dimethylaniline (Spec: <2 parts per million by weight (ppm). [0136] The solvent was distilled under vacuum (recovered) and the resultant dark brown liquid was purified by high vacuum distillation to give 71 g (Yield: 90percent) of pure para- eugenol (distilled at 112-116 °C at -10-12 mbar) with purity 99.7percent.

96% With toluene-4-sulfonic acid In neat (no solvent, solid phase) at 20℃; for 0.583333 h; Green chemistry General procedure: MOM ether (5 mmol) and pTSA.H2O (7.7 mmol) weretriturated well in a mortar for 5 min (in the case of entry 10trituration time was about 15 min), reaction mixture was leftat room temperature for another 30 min. After completion ofthe reaction (monitored by TLC), cold water (4oC) wasadded. The products were separated by centrifugation. Theyields of the products ranged from 85-98percent. The purities andthe identities of the products were established by direct comparisonwith known compounds (TLC, Mp and IR). See supplementaryinformation for further details.
89% With bismuth(III) chloride In water; acetonitrile at 50℃; for 1 h; General procedure: BiCl3 (30 molpercent) was added to a stirred solution of MOM-protected phenol (1 mmol) in MeCN/H2O (5:0.1 mL; 5:0.1 v/v) and the mixture was stirred at 50 °C until reaction was complete (TLC control). The mixture was filtered over a pad of celite using CH2Cl2 (10 mL), and the resulting filtrate was dried over anhydrous sodium sulfate, filtered, and concentrated under reduced pressure. Flash column chromatography of the residue over silica gel (hexane/EtOAc mixture) afforded the desired pure phenol (76–95percent). All phenolic products were analyzed by IR and NMR spectroscopy and by comparison with authentic samples.

87% With sodium tetrachloroaurate (III) dihydrate In methanol at 20℃; for 7 h; NaAuCl4·2 H2O (39.8 mg, 0.1 mmol, 0.05 equiv) was added to a solution of silyl ether 1030 (557 mg, 2 mmol) in MeOH (4 mL) at r.t., and the mixture was stirred at r.t. for 7 h. The mixture was then diluted with EtOAc (10 mL), filtered through activated alumina, and concentrated in vacuo. The residue was purified by flash column chromatography[silica gel, EtOAc–PE (1:5)] to give a pale-yellow oil; yield: 286mg (87percent). 1H NMR (300 MHz, CDCl3): δ = 6.86–6.83 (m, 1 H), 6.69–6.67 (m, 2 H),5.99–5.88 (m, 1 H), 5.49 (s, 1 H), 5.10–5.04 (m, 2 H), 3.87 (s, 3 H), 3.32(d, J = 6.6 Hz, 2 H).13C NMR (75 MHz, CDCl3): δ = 146.44, 143.92, 137.80, 131.89, 121.17,115.45, 114.26, 111.14, 55.83, 39.84.MS (ESI, MeOH): m/z = 187 [M + Na]+.HRMS-ESI: m/z [M + Na]+ calcd for C10H12NaO2: 187.0735; found:187.0735.

76 %Spectr. at 200℃; for 0.0333333 h; Microwave irradiation To a 5ml_ Biotage® microwave vial fitted with a magnetic stirrer, was charged with calcium bis-triflimide (16 mg, 26.7 μιτιοΙ) and O-allylguaiacol (438 mg, 2.67 mmol). The vial was then sealed and the resultant homogeneous mixture was stirred for 2 minutes at the temperature of 200°C, under an autogenous pressure and a microwave irradiation generated by the Biotage® microwave instrument. After cooling to room temperature, the resulting reaction mixture was analysed by 1H NMR to determine the conversion ratio (100percent) and isomeric composition (76percent of ortho- eugenol and 24percent of para- eugenol).
