“…In 2001, an alternative synthesis for this class of compounds from phenylaminobutadienes was reported. Heating the halonitrodienes 32 in methanol or acetic acid leads to the formation 2‐(1‐nitro‐trihalo‐2‐propenylidene)benzazetidines 2 k in good yields (Scheme ) …”

Benzazetidines are a class of N‐heterocycles potentially very interesting for a variety of purposes, including biological applications and drug design. In the past, their high ring strain has hampered the development of trustable, general, and efficient synthetic methodologies for their preparation. In this review article, the aim is to disclose all the literature contributions about the synthesis of these compounds and the study of their reactivity, from the early examples to the most recent synthetic approaches. Recently, there has been a growth of interest for this heterocycle, driven by the publication of novel synthetic methodologies based on palladium‐catalyzed intramolecular C−H amination and organocatalyzed ring‐closure of 2‐(N‐Boc‐anilino)‐α‐ketoesters/amides.

“…Thus, when the latter are heated in proton-donating solvents (methanol, acetic acid, 55-60°C, 10 h) the corresponding azole is eliminated, and 2-(1-nitrohalopropenylidene)-4-R-benzazetines 29a-f are formed [10,11,[30][31][32]. When the reaction is carried out in any of the above-mentioned solvents the yields of the alkoxysubstituted products 29a-c,e,f amount to 70-91%.…”

Published information on methods for the production of benzazetines and their dehydro derivatives (benzazetes) and their chemical transformations is reviewed and analyzed. It was noted that benzazetines with an unsubstituted NH group are unstable and their stable representatives have only became accessible in recent years. The tendency of benzazetines to undergo opening of the fourmembered heterocycle and isomerization processes was demonstrated. The wide-ranging synthetic possibilities of benzazetines and benzazetes are indicated.

“…27 Benzoazetine derivatives (A3) have received much attention as potential precursors for the generation of different types of products. [28][29][30][31] Although several studies on the formation of benzoazetine derivatives have been published, [32][33][34][35][36][37][38] numerous efforts have been made to synthesize "stable" benzoazetines that are convenient to use. These efforts have been only marginally successful.…”
