Twenty four tetrahydropyran esters were synthesized and tested as attractants toward Blattella germanica and Supella longipalpa in the laboratory by using the choice-chamber method. In general, carboxylates were superior to propionates and acetates. Among the 2-, 3-, or 4-substituted esters, substitution at the 4-position was better than at the other two positions. These results are explained in terms of the receptor model proposed earlier by others. In the experiment, the researchers used many compounds, for example, Ethyl 2-(tetrahydro-2H-pyran-4-yl)acetate (cas: 103260-44-2Recommanded Product: 103260-44-2).
Ethyl 2-(tetrahydro-2H-pyran-4-yl)acetate (cas: 103260-44-2) belongs to tetrahydropyran derivatives. Tetrahydropyran is a useful synthetic intermediate. Tetrahydropyranyl (THP-) ethers derived from the reaction of alcohols and dihydropyran are common intermediates in organic synthesis. The bismuth chloride-assisted cross-cyclization between homoallylic alcohols and epoxides provided various benzyl tetrahydropyran derivatives. The reaction afforded good yields of desired products and occurred under mild conditions.Recommanded Product: 103260-44-2
