The transformation proceeds through nitrogen insertion, followed by a subsequent 1,6-aza-Michael addition with p-quinone methides, enabling efficient C\u2013N bond formation. Notably, the developed method operates under mild, transition-metal-free conditions and is performed under an open-air atmosphere, offering a practical and environmentally benign approach to structurally diverse benzotriazoles and demonstrated 34 examples of \u226487% yield with wide functional group tolerance.<\/jats:p>","DOI":"10.1021\/acs.joc.6c00862","type":"journal-article","created":{"date-parts":[[2026,7,20]],"date-time":"2026-07-20T16:04:26Z","timestamp":1784563466000},"page":"10414-10424","source":"Crossref","is-referenced-by-count":0,"title":["Base Mediated Sequential\nNitrogen Insertion and Benzotriazolation\nof\n                    <i>p<\/i>\n                    -Quinone Methides"],"prefix":"10.1021","volume":"91","author":[{"given":"Ajay G.","family":"Mamale","sequence":"first","affiliation":[{"name":"CSIR-National Chemical Laboratory (CSIR-NCL) , , Dr. Homi Bhabha Road , ,","place":["Pune, India, 411 008"]},{"name":"Academy of Scientific and Innovative Research (AcSIR), CSIR-HRDC Campus , Sector 19, Kamla Nehru Nagar , ,","place":["Ghaziabad, India, 201 002"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Balaji M.","family":"Ghodake","sequence":"additional","affiliation":[{"name":"CSIR-National Chemical Laboratory (CSIR-NCL) , , Dr. Homi Bhabha Road , ,","place":["Pune, India, 411 008"]},{"name":"Academy of Scientific and Innovative Research (AcSIR), CSIR-HRDC Campus , Sector 19, Kamla Nehru Nagar , ,","place":["Ghaziabad, India, 201 002"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9162-522X","authenticated-orcid":true,"given":"Asish K.","family":"Bhattacharya","sequence":"additional","affiliation":[{"name":"CSIR-National Chemical Laboratory (CSIR-NCL) , , Dr. Homi Bhabha Road , ,","place":["Pune, India, 411 008"]},{"name":"Academy of Scientific and Innovative Research (AcSIR), CSIR-HRDC Campus , Sector 19, Kamla Nehru Nagar , ,","place":["Ghaziabad, India, 201 002"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2026,7,20]]},"reference":[{"key":"2026073108244927600_cit1a","doi-asserted-by":"publisher","DOI":"10.1016\/j.rechem.2022.100606","article-title":"A review on biological and medicinal\nimpact of heterocyclic compounds","volume":"4","author":"Kabir","year":"2022","journal-title":"Result Chem."},{"key":"2026073108244927600_cit1b","doi-asserted-by":"publisher","first-page":"35509","DOI":"10.1039\/D5RA06028A","article-title":"Recent advances\nin non-conventional synthesis of N-heterocyclic compounds: emerging\nstrategies and biological perspectives","volume":"15","author":"Sivaraj","year":"2025","journal-title":"RSC\nAdv."},{"key":"2026073108244927600_cit1c","doi-asserted-by":"publisher","first-page":"1909","DOI":"10.3390\/molecules25081909","article-title":"A Review on Recent Advances in Nitrogen-Containing\nMolecules and Their Biological Applications","volume":"25","author":"Kerru","year":"2020","journal-title":"Molecules"},{"key":"2026073108244927600_cit1d","doi-asserted-by":"publisher","first-page":"143","DOI":"10.1016\/j.ejmech.2016.09.023","article-title":"Structure-activity relationship (SAR) study and design\nstrategies of nitrogen-containing heterocyclic moieties for their\nanticancer activities","volume":"125","author":"Akhtar","year":"2017","journal-title":"Eur.
