The reactions proceeded by a new iron\u2010catalyzed cascade of alkynylation\/hydration by using both the \u03c3\u2010 and \u03c0\u2010Lewis acid properties of iron salts. The alkynylation reactions of several endo and exocyclic acetoxylactams were achieved with three different catalysts including FeCl<jats:sub>3<\/jats:sub>\u2009\u22c5\u20096H<jats:sub>2<\/jats:sub>O, FeCl<jats:sub>3<\/jats:sub>, and Fe(OTf)<jats:sub>3<\/jats:sub> showing the efficiency of \u03c3\u2010Lewis acidity of iron (III) salts in catalyzing the alkynylation reaction. We also demonstrated that the reaction sequence could be shortened by the direct use of hydroxylactams, leading to an environmentally friendly protocol, avoiding the need to perform unnecessary lengthy steps. A combination of the hard\/soft iron Lewis acid properties was then used to implement an unprecedented tandem intermolecular alkynylation\/intramolecular hydration sequence allowing expedient access to a new carbonyl structures from trivial materials.<\/jats:p>","DOI":"10.1002\/chem.202102357","type":"journal-article","created":{"date-parts":[[2021,8,3]],"date-time":"2021-08-03T22:07:15Z","timestamp":1628028435000},"page":"15440-15449","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Autotandem Catalysis: Inexpensive and Green Access to Functionalized Ketones by Intermolecular Iron\u2010Catalyzed Amidoalkynylation\/Hydration Cascade Reaction via <i>N<\/i>\u2010Acyliminium Ion Chemistry"],"prefix":"10.1002","volume":"27","author":[{"given":"Sidi Mohamed","family":"Abdallahi","sequence":"first","affiliation":[{"name":"Normandie Univ.
