This cascade photochemical transformation proceeds via an unprecedented intermolecular radical addition, an intramolecular ring closure, and a 1,2-alkyl\/aryl shift. Notably, this process is highly atom-economic; the initial acyl C\u2013H activation is feasible under mild conditions without the use of additives or external reagents. The strategy is compatible with various aldehydes and diverse N-(2-ethynylaryl)amides, delivering structurally diverse 3,3-disubstituted oxindoles, including structurally diverse drug derivatives and other synthetic extensions.<\/jats:p>","DOI":"10.1021\/acs.orglett.6c02807","type":"journal-article","created":{"date-parts":[[2026,8,4]],"date-time":"2026-08-04T14:35:16Z","timestamp":1785854116000},"page":"10314-10321","source":"Crossref","is-referenced-by-count":1,"title":["Radical Relay\nMeets Migration: TBADT-Catalyzed Access\nto 3,3-Disubstituted Oxindoles via Alkyl\/Aryl Shift"],"prefix":"10.1021","volume":"28","author":[{"given":"Punith S.","family":"Gowda","sequence":"first","affiliation":[{"name":"Indian Institute of Technology Hyderabad , , Kandi , , ,","place":["Sangareddy, Telangana, India, 502284"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jagadeesh Reddy","family":"Thondur","sequence":"additional","affiliation":[{"name":"Indian Institute of Technology Hyderabad , , Kandi , , ,","place":["Sangareddy, Telangana, India, 502284"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Duddu S.","family":"Sharada","sequence":"additional","affiliation":[{"name":"Pondicherry University , , , ,","place":["Pondicherry, India, 605014"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6410-5421","authenticated-orcid":true,"given":"Gedu","family":"Satyanarayana","sequence":"additional","affiliation":[{"name":"Indian Institute of Technology Hyderabad , , Kandi , , ,","place":["Sangareddy, Telangana, India, 502284"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2026,8,3]]},"reference":[{"key":"2026081410101832800_cit1a","doi-asserted-by":"publisher","first-page":"537","DOI":"10.1016\/j.ejmech.2013.08.030","article-title":"3,3-Disubstituted\nOxindoles as Potent Inhibitors of Akt Signaling","volume":"69","author":"Denoyelle","year":"2013","journal-title":"Eur.
