• Verwenden

  The catalytic system of disubstituted aromatics was optimized for the 2-methylanisole reduction by a proper choice of the amine/Rh ratio which should be high enough to stabilize very small colloidal rhodium particles and low enough to avoid deactivation. The total synthesis of (±)-heliannuol D and its epimer has been completed in 9 steps and 12% overall yield from 2-methylanisole. The thermal activation of 2-methylanisole (60°C) by the Ir (III) complex TpMe2Ir (C6H5) 2 (N2)(1; TpMe2= hydrotris (3, 5-dimethylpyrazolyl) borate) yielded a mixture of hydride complexes. The total synthesis of the phenolic sesquiterpene mutisianthol has been accomplished in 12 steps from the readily available 2-methylanisole. The catalytic system was optimized for the 2-methylanisole reduction by a proper choice of the amine/Rh ratio which should be high enough to stabilize very small colloidal rhodium particles and low enough to avoid deactivation.

• Definition

  ChEBI: 2-methylanisole is a monomethoxybenzene that is o-cresol in which phenolic hydroxy group has been converted to the corresponding methyl ether. A 'green' solvent (b.p. 171°C) and food flavour ingredient, it is found in mastic oils, virgin olive oils and frankincense. It has a role as a polar aprotic solvent and a flavouring agent. It is a monomethoxybenzene, a volatile organic compound and a member of toluenes. It derives from an o-cresol.

• synthetische

  2-Methylanisole is synthesized by methylation of o-cresol using dimethylsulfate in caustic soda at 40°C.
  synthesis of 2-methylanisole: Make sodium hydroxide into a 20% solution, stir and mix with o-cresol, cool to below 10°C, and slowly add dimethyl sulfate dropwise. After the addition was completed, the temperature was raised to 40 °C for 20 min, and then reacted with 100 °C for 12 h. Then the reactant was washed with water until neutral, water was removed, distilled, and the fraction at 171°C was collected to obtain the finished product of 2-methylanisole.

• Aroma threshold values

  Detection: 600 ppb. Aroma characteristics at 1.0%: naphthyl, camphoreous, phenolic and woody with a salicylate nuance.

• Taste threshold values

  Taste characteristics at 5.0 ppm: camphoreous, earthy, woody and alicylate with minty, spicy nuances.

• Allgemeine Beschreibung

  2-Methylanisole is found in mastic oils, virgin olive oils and frankincense. It is a monomethoxybenzene and acts as an intermediate for the preparation of compounds with methylhydroquinone core.

• Flammability and Explosibility

  Flammable
