The three-point interaction mechanisms require the fair geometrical fitting and functional group compatibility of the interacting groups. Structure–chiral selectivity correlations are guidelines that can be established via trough systematic studies using model compounds. The enantiorecognition of the test compounds was studied on an octakis 2,3-Di-O-acetyl-6-O-tert-butyldimethylsilyl-gamma-cyclodextrin (TBDMSDAGCD) chiral selector. In our work, mandelic acid and its variously substituted compounds were used as model compounds to establish adaptable rules for other enantiomeric pairs. The mandelic acid and its modified compounds were altered at both their carboxyl and hydroxyl positions to test the key interaction forces of the chiral recognition processes. Ring- and alkyl-substituted mandelic acid derivatives were also used in our experiments. The chiral selectivity values of 20 test compounds were measured and extrapolated to 100 °C. The hydrogen donor abilities of test compounds improved their chiral selectivities. The inclusion phenomenon also played a role in chiral recognition processes in several cases. Enantiomer elution reversals were observed for different derivatives of hydroxyl groups, providing evidence for the multimodal character of the selector. The results of our research can serve as guidelines to achieve appropriate chiral separation for other enantiomeric pairs.}, year = {2023}, eissn = {1422-0067}, orcid-numbers = {Bodáné Kendrovics, Rita/0000-0002-6944-2515; Kaleta, Zoltán/0000-0003-2350-5100; Riszter, Gergő Attila/0000-0002-0487-5504} } @article{MTMT:33318067, title = {Chiral Separations of Pyrethroic Acids Using Cyclodextrin Selectors}, url = {https://m2.mtmt.hu/api/publication/33318067}, author = {Juvancz, Zoltán and Bodáné Kendrovics, Rita and Laczkó, Zita and Iványi, Róbert and Varga, Erzsébet}, doi = {10.3390/molecules27248718}, journal-iso = {MOLECULES}, journal = {MOLECULES}, volume = {27}, unique-id = {33318067}, issn = {1420-3049}, abstract = {Pyrethroid insecticides are broadly used. They have low toxicity for warm-blooded living creatures, but high toxicity for both insects and fish. Therefore, it is important to reduce the environmental impact of pyrethroids. Pyrethroic acids are chiral compounds. An effective way to decrease pollution is to use enantio-pure insecticide products instead of their racemic mixtures. Enantiomer-pure products require enantiomer selective synthesis and analysis. The chiral selective analysis of pyrethroic acids (an intermediate of pyrethroids) is also important in terms of process control and from the point of view of their degradation metabolism in the environment. This study used various enantiomeric selective chromatographic methods for the separation of different pyrethroic acids, including gas chromatography, supercritical fluid chromatography and capillary electrophoresis. Systematic experiments were conducted to find the optimum conditions for their chiral separation. The employed enantio-selective agents were cyclodextrin derivatives with different ring sizes and substitution patterns. The β-cyclodextrin proved to be excellent for the chiral separation of these acids. The different chiral recognition mechanisms were established using different ring-sized cyclodextrins. The results of these systematic studies demonstrated the correlations of the chiral selectivity features of selectors and the structures of analytes.}, year = {2022}, eissn = {1420-3049}, orcid-numbers = {Bodáné Kendrovics, Rita/0000-0002-6944-2515} } @inproceedings{MTMT:33251547, title = {KÖRNYEZETI SZEMPONTBÓL FONTOS MANDULASAV-SZÁRMAZÉKOK ENANTIOMER SZELEKTÍV GÁZKROMATOGRÁFIÁS ELVÁLASZTÁSA GAMMA CIKLODEXTRIN SZELEKTORON}, url = {https://m2.mtmt.hu/api/publication/33251547}, author = {RÉPÁSSY, Levente and Juvancz, Zoltán and Bodáné Kendrovics, Rita}, booktitle = {REJTŐ ’50’ JUBILEUMI KONFERENCIA}, unique-id = {33251547}, year = {2022}, pages = {250-259}, orcid-numbers = {Bodáné Kendrovics, Rita/0000-0002-6944-2515} } @{MTMT:33124704, title = {Chapter VII.}, url = {https://m2.mtmt.hu/api/publication/33124704}, author = {Bodáné Kendrovics, Rita and Juvancz, Zoltán}, booktitle = {New Challenges of the Century: Textbook}, unique-id = {33124704}, year = {2022}, pages = {237-250}, orcid-numbers = {Bodáné Kendrovics, Rita/0000-0002-6944-2515} } @article{MTMT:33124697, title = {Combination of energy production and plastic waste management}, url = {https://m2.mtmt.hu/api/publication/33124697}, author = {Juvancz, Zoltán and László, Tolner}, journal-iso = {IJLRET}, journal = {INTERNATIONAL JOURNAL OF LATEST RESEARCH IN ENGINEERING AND TECHNOLOGY}, volume = {&}, unique-id = {33124697}, year = {2022}, eissn = {2454-5031}, pages = {1-7} } @inproceedings{MTMT:33089206, title = {CHIRAL SEPARATIONS OF PHYRETROIC ACIDS USING CYCLODEXTRIN SELECTORS}, url = {https://m2.mtmt.hu/api/publication/33089206}, author = {Juvancz, Zoltán and Bodáné Kendrovics, Rita and Zita, LACZKÓ}, booktitle = {Proceedings of VI.
