Azetidine synthesis enabled by photo-induced copper catalysis via [3+1] radical cascade cyclization
The Innovation, 2022 Azetidines are an important type of saturated, highly strained, four-membered, nitrogen-containing heterocyclic compound. These compounds serve as important raw materials, intermediates, and catalysts in organic synthesis, as well as important active ...

The Polymerization of Azetidines and Azetidine Derivatives [PDF]
Polymer Journal, 1980 The cationic ring-opening polymerization of azetidine, N-alkylazetidines and a number of azetidines carrying a second functional group is reviewed. Some of these monomers lead to “living” polymers. The rate constants for the polymerization of different azetidines are discussed and compared with the rate constants for the polymerization of other four ...

Molecules, 2022 In this work it is demonstrated that enantiomerically enriched N-alkyl 2-oxazolinylazetidines undergo exclusive α-lithiation, and that the resulting lithiated intermediate is chemically stable but configurationally labile under the given experimental ...

Intermolecular 2+2 imine-olefin photocycloadditions enabled by Cu(I)-alkene MLCT
Nature Communications, 2022 An ideal method to construct azetidines would be through a [2 + 2] photocycloaddition that joins an olefin and an imine, shown only rarely in the literature, partially due to competitive photochemical processes of the imine.

Azetidines. II. Some Functional Derivatives of Azetidines [PDF]
Bulletin of the Chemical Society of Japan, 1967 Abstract The sodium methoxide-catalyzed cyclization of methyl α-tosylamino-γ-chlorobutyrate gave methyl 1-tosylazetidine-2-carboxylate, which was then converted to the corresponding carboxylic acid and carbinol. 1-Acetyl-2,2,4,4-tetramethylazetidine-3-carboxylic acid was prepared by the photolysis of 1-acetyl-4-diazo-2,2,5,5 ...
