Zhang, Xinyu published the artcileFluorocyclization of Allyl Alcohols and Amines to Access 3-Functionalized Oxetanes and Azetidines, Safety of 4-Chloro-3-(trifluoromethyl)benzenesulfonyl Chloride, the publication is Organic Letters (2021), 23(9), 3674-3679, database is CAplus and MEDLINE.
An efficient method to prepare 3-functionalized oxetanes and azetidines I [R1 = H, Me, Ph, etc.; R2 = Me, Ph, 2-FC6H4, etc.; R1R2 = (CH2)4, (CH2)5, (CH2)2O(CH2)2, etc.; X = O, NC(O)Ph, NSO2Ph, etc.] was realized by fluorocyclization of readily available 2-azidoallyl alcs. and amines. Notably, this was the first example applying the fluorocyclization strategy to construct four-membered heterocycles. The pendant electron-donating group (-N3 or -OR) played a crucial role in polarizing the C=C double bond and facilitating the cyclization process, as verified by DFT and exptl. studies.
