General Description

2,4-DIMETHYL-6-PHENYL-DIHYDROPYRAN, also known as vetiverol, is a chemical compound that belongs to the family of pyrans. It is a colorless to pale yellow liquid with a sweet, floral odor, and is commonly used in the manufacturing of perfumes and other fragrance products. Vetiverol is also found naturally in the essential oils of certain plants, particularly in the roots of vetiver grass. It is known for its calming and relaxing properties, and is often used in aromatherapy for its ability to reduce stress and anxiety. Additionally, vetiverol has the potential to act as a pheromone for certain insect species, and may have applications in pest control.

Process for preparing dihydropyrane compound

To provide a simple process for economically preparing a dihydropyrane compound at a high productivity and a high reaction yield. To use a compound selected from the group consisting of a base and a compound (VIII) having a weaker coordination power to the Lewis acid than the aldehyde compound and having an activity to dissolve the Lewis acid, coordinated by the compound (VIII), in a solvent as a co-catalyst in reacting aldehyde with a diene compound in the presence of a Lewis acid to prepare a 5,6-dihydro-2H-pyrane compound represented by formula (III): STR1 in which R1 represents a hydrogen atom, an alkyl group having 1 to 12 carbon atoms, aryl group which may be substituted with alkyl group, having 6 to 12 total carbon atoms; R2 and R3 represent a hydrogen atom or an alkyl group having 1 to 6 carbon atoms.

Trifluoromethanesulfonic acid, an efficient catalyst for the hetero Diels-Alder reaction and an improved synthesis of mefrosol

Trifluoromethanesulfonic (triflic) acid (1 mol%) has been found to be an efficient catalyst for the hetero Diels-Alder reaction between aromatic aldehydes and unactivated dienes.

CONCERNING THE PRODUCTS OBTAINED FROM THE CONDENSATION OF 4-METHYL-4-PENTEN-2-OL WITH BENZALDEHYDE

The products formed in the condensation reaction of 4-methyl-4-penten-2-ol with benzaldehyde were reinvestigated.Their constitutions and configurations were determined spectroscopically.For further characterisation, the three olefins 8-10 were epoxidised.
