Kokuev AO, Sukhorukov AY. Michael addition of P-nucleophiles to azoalkenes provides simple access to phosphine oxides bearing an alkylhydrazone moiety. Front Chem 2023; 11:1177680. [PMID: 37123875 PMCID: PMC10133514 DOI: 10.3389/fchem.2023.1177680] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2023] [Accepted: 03/27/2023] [Indexed: 05/02/2023] Open
Abstract
β-Hydrazonophosphine oxides are precursors of useful organophosphorus compounds, including phosphorylated N-heterocycles, α-aminophosphonates, and vinylphosphonates. In this work, a general transition metal-free synthesis of β-hydrazonophosphine oxides was developed. The method relies on the Michael addition of phosphine oxides R2P(O)H to reactive azoalkenes (1,2-diaza-1,3-butadienes), which are generated in situ from α-halohydrazones and Hunig's base. The reaction stereoselectively leads to Z-isomers of β-hydrazonophosphine oxides that are stabilized by intramolecular hydrogen bonding. The conversion of the products thus obtained into potential chelating ligands was showcased.

Abstract
Substituted hydroxy-benzofurans are easily accessible by treatment of resorcinols and 1,2-diaza-1,3-dienes (DDs) under acidic conditions. The reaction happens through an uncommon Michael reaction between aromatic derivatives as aromatic C(sp2)-H nucleophiles and DDs as acceptors. Also, the behavior of different phenols and 2-naphthol was investigated.

Abstract
The base-induced unprecedented tandem [4 + 2] and [1 + 2] annulation reaction of in situ formed 1,2-diaza-1,3-dienes and crotonate-derived sulfur ylides is reported. This protocol provides a novel and practical method for the synthesis of cyclopropane-fused tetrahydropyridazines with a quaternary carbon center in synthetically useful yield. In this tandem reaction, three new bonds were formed in one pot, and the crotonate-derived sulfur ylide serves as a C3 synthon.

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.
