This method uses cyclic allylborates, a sulfur dioxide surrogate (DABSO), and organic halides such as alkyl halides and allylic bromides. The reaction proceeds with high \u03b1-selectivity, which is notable since \u03b3-selective functionalization is more common for allylic boron compounds. The reaction demonstrates a broad substrate scope with respect to both the cyclic allylborates and organic halides. Mechanistic investigations suggest that the reaction proceeds via the initial formation of a \u03b3-functionalized SO2 intermediate, followed by a rearrangement to afford the final \u03b1-product.<\/jats:p>","DOI":"10.1021\/acs.orglett.6c03461","type":"journal-article","created":{"date-parts":[[2026,9,9]],"date-time":"2026-09-09T04:02:00Z","timestamp":1788926520000},"page":"11774-11778","source":"Crossref","is-referenced-by-count":0,"title":["Sulfonylation\nof Cyclic Allylborates with DABSO: Synthesis\nof Allylic Sulfones Having an Allylic Boronate Moiety"],"prefix":"10.1021","volume":"28","author":[{"given":"Hiroki","family":"Murata","sequence":"first","affiliation":[{"name":"Kyoto University , , Nishikyo-ku , ,","place":["Kyoto, Japan, 615-8510"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yusaku","family":"Uemura","sequence":"additional","affiliation":[{"name":"Kyoto University , , Nishikyo-ku , ,","place":["Kyoto, Japan, 615-8510"]},{"name":"Kyoto University , , Nishikyo-ku , ,","place":["Kyoto, Japan, 615-8510"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Go","family":"Yamagiwa","sequence":"additional","affiliation":[{"name":"Kyoto University , , Nishikyo-ku , ,","place":["Kyoto, Japan, 615-8510"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7903-4091","authenticated-orcid":true,"given":"Kazuhiko","family":"Semba","sequence":"additional","affiliation":[{"name":"Kyoto University , , Nishikyo-ku , ,","place":["Kyoto, Japan, 615-8510"]},{"name":"Kyoto University , , Nishikyo-ku , ,","place":["Kyoto, Japan, 615-8510"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6687-2528","authenticated-orcid":true,"given":"Tetsuaki","family":"Fujihara","sequence":"additional","affiliation":[{"name":"Kyoto University , , Nishikyo-ku , ,","place":["Kyoto, Japan, 615-8510"]},{"name":"Kyoto University , , Nishikyo-ku , ,","place":["Kyoto, Japan, 615-8510"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2026,9,8]]},"reference":[{"key":"2026091809431976900_cit1a","doi-asserted-by":"publisher","DOI":"10.1002\/tcr.202500136","article-title":"Synthesis of Allylic Sulfones via Generation of Metal\n\u03a0-Allyl Complexes in Metal-Catalyzed Sulfonylation","volume":"25","author":"Zhang","year":"2025","journal-title":"Chem.
