Derivatives of 5,6-dihydro-2H-pyran-3-carboxylic acid was written by Spreitzer, Helmut;Mueller, Petra;Buchbauer, Gerhard. And the article was included in Monatshefte fuer Chemie in 1990.Computed Properties of C6H8O2 This article mentions the following:
Some derivatives of 5,6-dihydro-2H-pyran-3-carboxaldehyde (I, R = CHO) and of its oxidation product, 5,6-dihydro-2H-pyran-3-carboxylic acid I (R = CO2H), were prepared The aldehyde derivatives as well as amides and esters of I (R = CO2H) were tested in an insecticidal/fungicidal/acaricidal screening program. The Me ester I (R = CO2Me) shows a distinct knock down effect against the fruit fly Drosophila melanogaster. In the experiment, the researchers used many compounds, for example, 5,6-Dihydro-2H-pyran-3-carbaldehyde (cas: 13417-49-7Computed Properties of C6H8O2).
5,6-Dihydro-2H-pyran-3-carbaldehyde (cas: 13417-49-7) belongs to tetrahydropyran derivatives. Tetrahydropyran is an important raw material and intermediate used in Organic Synthesis, Pharmaceuticals, Agrochemicals and dyestuff. 2-(Arylmethylene)cyclopropylcarbinols could be converted to the corresponding tetrahydropyrans stereoselectively in the presence of Brønsted acids under mild conditions. A plausible Prins-type reaction mechanism has been proposed.Computed Properties of C6H8O2
