These structures were unambiguously determined, including single\u2010crystal XRD analysis for two compounds. The stability, acid\/base and electronic properties of these dipolar phosphorus heterocycles were subsequently investigated. zPHCs can be successfully employed as a new class of chiral solvating agents for the enantiodifferentiation of chiral carboxylic and sulfonic acids by NMR spectroscopy. The stoichiometry and binding constants for the donor\u2013acceptor complexes formed were established by NMR titration methods.<\/jats:p>","DOI":"10.1002\/chem.201300062","type":"journal-article","created":{"date-parts":[[2013,4,18]],"date-time":"2013-04-18T14:59:01Z","timestamp":1366297141000},"page":"8136-8143","source":"Crossref","is-referenced-by-count":12,"title":["New Chiral Zwitterionic Phosphorus Heterocycles: Synthesis, Structure, Properties and Application as Chiral Solvating Agents"],"prefix":"10.1002","volume":"19","author":[{"given":"Andrey E.","family":"Sheshenev","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ekaterina V.","family":"Boltukhina","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anastasiya A.","family":"Grishina","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ivana","family":"Cisa\u0159ova","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ilya M.","family":"Lyapkalo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"King Kuok (Mimi)","family":"Hii","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2013,4,18]]},"reference":[{"key":"e_1_2_6_1_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.trac.2010.12.003"},{"key":"e_1_2_6_2_2","doi-asserted-by":"publisher","DOI":"10.1080\/05704920902717971"},{"key":"e_1_2_6_3_2","doi-asserted-by":"publisher","DOI":"10.1021\/cr00007a009"},{"key":"e_1_2_6_4_2","unstructured":"\u00a0"},{"key":"e_1_2_6_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.pnmrs.2010.07.003"},{"key":"e_1_2_6_6_2","doi-asserted-by":"publisher","DOI":"10.1002\/chir.20478"},{"key":"e_1_2_6_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.tetasy.2011.09.018"},{"key":"e_1_2_6_8_2","doi-asserted-by":"publisher","DOI":"10.1021\/ja00483a035"},{"key":"e_1_2_6_9_2","doi-asserted-by":"publisher","DOI":"10.1007\/BF00957149"},{"key":"e_1_2_6_10_2","doi-asserted-by":"publisher","DOI":"10.1007\/BF00957516"},{"key":"e_1_2_6_11_2","doi-asserted-by":"publisher","DOI":"10.1021\/ja00002a080"},{"key":"e_1_2_6_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0957-4166(97)00593-4"},{"key":"e_1_2_6_13_2","doi-asserted-by":"publisher","DOI":"10.1021\/cr040642v"},{"key":"e_1_2_6_14_2","doi-asserted-by":"publisher","DOI":"10.1021\/cr0505324"},{"key":"e_1_2_6_15_2","doi-asserted-by":"publisher","DOI":"10.1021\/cr800400z"},{"key":"e_1_2_6_16_2","doi-asserted-by":"publisher","DOI":"10.1002\/ejoc.200600133"},{"key":"e_1_2_6_17_2","first-page":"572","author":"Ramalingam B.","year":"2007","journal-title":"Synthesis"},{"key":"e_1_2_6_18_2","doi-asserted-by":"publisher","DOI":"10.1021\/jo070534j"},{"key":"e_1_2_6_19_2","doi-asserted-by":"publisher","DOI":"10.1021\/ja00213a033"},{"key":"e_1_2_6_20_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.tetasy.2008.06.012"},{"key":"e_1_2_6_21_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.tetasy.2011.01.013"},{"key":"e_1_2_6_22_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0957-4166(97)00586-7"},{"key":"e_1_2_6_23_2","doi-asserted-by":"publisher","DOI":"10.1070\/MC1999v009n04ABEH001085"},{"key":"e_1_2_6_24_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.tetasy.2007.03.030"},{"key":"e_1_2_6_25_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.tetlet.2008.03.113"},{"key":"e_1_2_6_26_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.tetasy.2008.04.030"},{"key":"e_1_2_6_27_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.tetasy.2009.08.030"},{"key":"e_1_2_6_28_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.tetasy.2010.05.010"},{"key":"e_1_2_6_29_2","doi-asserted-by":"publisher","DOI":"10.1007\/s12039-010-0090-z"},{"key":"e_1_2_6_30_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.tetasy.2011.09.022"},{"key":"e_1_2_6_31_2","doi-asserted-by":"publisher","DOI":"10.1002\/chir.20948"},{"key":"e_1_2_6_32_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.chroma.2010.08.077"},{"key":"e_1_2_6_33_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0040-4020(00)00492-0"},{"volume-title":"Binding Constants: The Measurement of Molecular Complex Stability","year":"1987","author":"Connors K.
