New compounds open up prospects for the synthesis of other polyfunctional compounds combining a biologically active pinane fragment with various pharmacophore groups. It was shown that the syntheses of sulfanyl and sulfonyl derivatives based on 2-norpinanone are characterized by high stereoselectivity in comparison with similar reactions of pinocarvone. The conditions for the preparation of diastereomerically pure thioacetyl and thiobenzoyl derivatives based on pinocarvone, as well as for the chemoselective oxidation of \u03b3-ketothiols with chlorine dioxide to the corresponding thiolsulfonates and sulfonic acids, were selected. The effect of the VO(acac)2 catalyst on the increase in the yields of thiosulfonates was shown. A new direction of the transformation of thiosulfonates with the formation of sulfones was revealed. In the case of pinocarvone-based sulfones, the configuration is inversed at the C2 atom. An epimerization scheme is proposed.<\/jats:p>","DOI":"10.3390\/molecules26175245","type":"journal-article","created":{"date-parts":[[2021,8,31]],"date-time":"2021-08-31T04:07:28Z","timestamp":1630382848000},"page":"5245","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Synthesis and Oxidative Transformations of New Chiral Pinane-Type \u03b3-Ketothiols: Stereochemical Features of Reactions"],"prefix":"10.3390","volume":"26","author":[{"given":"Olga M.","family":"Lezina","sequence":"first","affiliation":[{"name":"Institute of Chemistry, FRC \u201cKomi Scientific Centre\u201d, Ural Branch of the Russian Academy of Sciences, Pervomayskaya St. 48, 167000 Syktyvkar, Komi Republic, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Svetlana N.","family":"Subbotina","sequence":"additional","affiliation":[{"name":"Institute of Chemistry, FRC \u201cKomi Scientific Centre\u201d, Ural Branch of the Russian Academy of Sciences, Pervomayskaya St. 48, 167000 Syktyvkar, Komi Republic, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Larisa L.","family":"Frolova","sequence":"additional","affiliation":[{"name":"Institute of Chemistry, FRC \u201cKomi Scientific Centre\u201d, Ural Branch of the Russian Academy of Sciences, Pervomayskaya St. 48, 167000 Syktyvkar, Komi Republic, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Svetlana A.","family":"Rubtsova","sequence":"additional","affiliation":[{"name":"Institute of Chemistry, FRC \u201cKomi Scientific Centre\u201d, Ural Branch of the Russian Academy of Sciences, Pervomayskaya St. 48, 167000 Syktyvkar, Komi Republic, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5640-6956","authenticated-orcid":false,"given":"Denis V.","family":"Sudarikov","sequence":"additional","affiliation":[{"name":"Institute of Chemistry, FRC \u201cKomi Scientific Centre\u201d, Ural Branch of the Russian Academy of Sciences, Pervomayskaya St. 48, 167000 Syktyvkar, Komi Republic, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,8,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"315","DOI":"10.1007\/s00005-007-0039-1","article-title":"Terpenes: Substances Useful in Human Healthcare","volume":"55","author":"Paduch","year":"2007","journal-title":"Arch.
