[PMID: 39005823 PMCID: PMC11238228 DOI: 10.1021/acsomega.4c00305] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/15/2024] [Revised: 02/29/2024] [Accepted: 03/27/2024] [Indexed: 07/16/2024]
Abstract
A new selective synthetic approach to indole derivatives bearing a tetrazole moiety has been developed. Arynes, generated in situ from o-(trimethylsilyl)aryl triflates and KF, reacted smoothly with 2-(2-benzyl-2H-tetrazol-5-yl)-2H-azirines to give 3-(2-benzyl-2H-tetrazol-5-yl)-indole derivatives with high selectivity. Deprotection of the tetrazole moiety gave 3-(1H-tetrazol-5-yl)-indole derivatives.

Abstract
N-Heterocyclic architectures are omnipresent in many bioactive natural
products, synthetic drugs, and materials science, thus have evoked a vast research interest
of academic, as well as industrial chemists. Recently, several efficient methods have been
developed for the preparation of various nitrogen-containing compounds with in situ generated
1,2-diaza-1,3-dienes from the easily available precursors including α -haloketohydrazones,
α-hydroxyl ketohydrazones, thiadiazole dioxides or their analogues, and
other simple hydrazones. These methods are considered powerful tools in the synthesis of
five-, six- and seven-membered ring heterocyclic compounds with good to excellent levels
of conversions and selectivities. This review mainly summarizes recent advances on the
chemistry of construction of versatile N-heterocycles from in situ generated 1,2-diaza-1,3-
dienes and presents an extensive summary of the application scopes and limitations of the corresponding cyclization
reactions. Moreover, enantioselective approaches are also covered.

Abstract
We developed an economical and practical protocol for the synthesis of 1,4,5,6-tetrahydropyridazines. A diverse range of alkoxyallenes and 1,2-diaza-1,3-dienes undergo (4 + 2) cycloaddition to generate the desired products in excellent yields. The high efficiency, wide substrate scope and good functional group tolerance of this process, coupled with operational simplicity, render the method synthetically attractive. The utility of the cycloaddition is also demonstrated by the preparation of various pyridazines from 1,4,5,6-tetrahydropyridazines. We developed an economical and practical protocol for the synthesis of 1,4,5,6-tetrahydropyridazines and pyridazines via cyclization of alkoxyallenes and 1,2-diaza-1,3-dienes.![]()

Abstract
Chiral multi-nitrogen-containing heterocycles, such as pyrazole, imidazole and pyridazine, are widely found in naturally occurring organic compounds and pharmaceuticals, and hence, their stereoselective and efficient synthesis is an important issue in organic synthesis. Out of the variety of methods that have been developed over the past century, the catalytic asymmetric cyclization and cycloaddition reactions are recognized as the most synthetically useful strategies due to their step-, atom- and redox-economic nature. In particular, the recently developed annulation reactions using azoalkenes as key intermediates show their great ability to construct diverse types of multi-nitrogen-containing heterocycles. In this feature article, we critically analyse the strategic development and the efficient transformation of azoalkenes to chiral heterocycles and α-functionalized ketone derivatives since 2010. The plausible mechanism for each reaction model is also discussed.

Abstract
A catalyst-free [4 + 2] annulation process between in situ generated 1,2-diaza-1,3-butadienes and simple olefins has been developed. Under mild conditions, the reactions afforded 1,4,5,6-tetrahydropyridazines, which feature a wide range of bioactive compounds, with high yields (up to 99% yield).
