Usage

General Description

2,3-Dimethyl-5-ethylpyrazine is a chemical compound that belongs to the group of pyrazines, which are commonly found in natural foods and are used in the flavor and fragrance industry. It is a colorless liquid with a strong, nutty, and slightly earthy odor. 2,3-Dimethyl-5-ethylpyrazine is often used in food products to add a roasted or nutty flavor, and it is also a common ingredient in the production of tobacco and chocolate flavors. Additionally, 2,3-Dimethyl-5-ethylpyrazine has been studied for its potential applications in pharmaceuticals and as a synthetic intermediate in organic chemistry. However,

Method for site-selective alkylation of Diazine-N-oxide using phosphonium ylides

- N - Oxide (Diazine -)N-The position selective Oxides-C alkylation of H) relates to a method alkylation. To the present invention, a plurality of diazine compounds can be alkylated by selectively introducing an alkyl group to a diazine compound known as a core unit structure in a medicine, and synthesis of a plurality of diazine compounds (varenicline) paenibacillin A, which is a natural product, can be synthesized.

Alkylations and hydroxymethylations of pyrazines via green minisci-type reactions

A new general methodology utilizing Minisci-type chemistry has been developed that cleanly and efficiently prepares alkyl- and (hydroxymethyl) pyrazines. The new methods eliminate toxic catalysts and halogenated solvents, providing a greatly improved route to these natural products which are prevalent in many natural systems as bacterial volatiles, plant volatiles, and insect pheromones.

Regioselective synthesis of trialkylpyrazines via nickel-catalyzed Negishi cross-coupling of pyrazine triflate

A regioselective synthesis of trialkylpyrazines via nickel-catalyzed cross-coupling reaction of pyrazine triflate is reported. The 5-substituted 2,3-dimethylpyrazine derivatives including trail pheromone components of the ant Eutetramorium mocquerysi have been successfully synthesized in good yields by nickel-catalyzed Negishi cross-coupling reactions of pyrazine triflate mediated by alkyl and arylzinc halides.
