Pandey, Karuna Shanker; Shriprakash; Pandey, Mamta; Rao, Karumuru Mallikarjuna; Vaidyanathaswamy, Ramamoorthy published the artcile< Synthesis and resolution of tetrahydropyran carboxylic acids and the bioevaluation of their esters as cockroach attractants>, Name: Methyl tetrahydro-2H-pyran-3-carboxylate, the main research area is tetrahydropyrancarboxylate attractant cockroach.
Tetrahydropyran-2- and 3-carboxylic acids were resolved by using quinine. The enantiomeric purity of the corresponding Me esters (I and II) was determined by proton NMR, using a lanthanide chiral shift reagent [Eu(hfc)3] in the ratio 1:3 (substrate/shift reagent). The relative attractant activity of the racemic, and (+) and (-) isomers of these esters was evaluated against Blattella germanica (L.) and Supella longipalpa (F.). The results show that the activity order for I was (-) > (+) > racemic, and for II was (+) > (-) > racemic.
Bioscience, Biotechnology, and Biochemistry published new progress about Blattella germanica. 18729-20-9 belongs to class esters-buliding-blocks, and the molecular formula is C7H12O3, Name: Methyl tetrahydro-2H-pyran-3-carboxylate.
