I found the field of Chemistry very interesting. Saw the article Mono- and dispirocyclotriphosphazenes containing 4-bromobenzyl pendant arm(s): Synthesis, spectroscopy, crystallography and biological activity studies published in 2020. Name: 1,4-Dioxa-8-azaspiro[4.5]decane, Reprint Addresses Asmafiliz, N (corresponding author), Ankara Univ, Dept Chem, TR-06100 Ankara, Turkey.. The CAS is 177-11-7.

The N/N donor-type bromobenzyldiamines (1-3) were successively prepared by reduction of Schiff bases formed as a result of condensation reactions of 4-bromobenzaldehyde with aliphatic diamines. The Cl exchange reactions of hexachlorocyclotriphosphazene (HCCP; trimer; N3P3Cl6; 4) with the bidentate ligands (1-3) produced the new monospiro- (5-7) and dispirocyclotriphosphazenes (8-13) containing 4-bromo-benzyl pendant arm(s). The tetrachloro phosphazenes (5-7) were reacted with pyrrolidine, tetra-1,4-dioxa-8-azaspiro [4.5]decane (DASD) and piperidine to give the tetraamino substituted mono-spirophosphazenes (5a-7c). The spectral analyses of all the phosphazenes were made using appropriate spectroscopic methods; such as FTIR, H-1, C-13, P-31 NMR and ESI-MS. The molecular and crystal structures of 5, 6, 7 and 12 were also determined by X-ray crystallography. On the other hand, the antimicrobial activities of the phosphazenes were evaluated against G (-) and G (+) bacteria and fungi. Some of the tetraaminophosphazenes were found to be very active against several bacteria and fungi. Besides, the interactions of the cyclotriphosphazenes with plasmid DNA were investigated using agarose gel electrophoresis. (C) 2020 Elsevier B.V. All rights reserved.

Metal-catalyzed cross-coupling reactions are among the most important transformations in organic synthesis. However, the use of C-H activation for sp(2) C-N bond formation remains one of the major challenges in the field of cross-coupling chemistry. Described herein is the first example of the synergistic combination of copper catalysis and electrocatalysis for aryl C-H amination under mild reaction conditions in an atom-and step-economical manner with the liberation of H-2 as the sole and benign byproduct.

In this study, we establish that conjugated enynes undergo selective 1,4-hydroamination under Pd catalysis to deliver chiral allenes with pendant allylic amines. Several primary and secondary aliphatic and aryl-substituted amines couple with a wide range of mono- and disubstituted enynes in a nonenantioselective reaction where DPEphos serves as the ligand for Pd. Benzophenone imine acts as an ammonia surrogate to afford primary amines in a two-step/one-pot process. Examination of chiral catalysts revealed a high degree of reversibility in the C-N bond formation that negatively impacted enantioselectivity. Consequently, an electron-poor ferrocenyl-PHOX ligand was developed to enable efficient and enantioselective enyne hydroamination.

The formation of nitrile oxides with diazocarbonyl compounds by nitrosyl transfer from tert-butyl nitrite under mild conditions and without the use of a catalyst or an additive is reported. This transformation is broadly applicable to the synthesis of furoxans by dimerization and isoxazoles and isoxazolines by cycloaddition. This methodology is also applied for the millimole-scale synthesis of two biologically active compounds. The formation of the nitrile oxide from a diazoacetamide is stable and confirmed experimentally.

Thienylzinc halides and related compounds prepared by deprotonation followed by transmetalation were used in copper-catalyzed amination using N-benzoyloxy secondary amines. By extending the reaction to 1,5-naphthyridine, it was showed that the competitive dimer formation observed in the case of thiophenes was linked with the low stability of some thienylamines rather than homocoupling. Interestingly, thienylzinc halides and related compounds prepared by transmetalation of thienylmagnesium halides, either prepared from their bromo-precursors or generated by deprotometalation, were satisfactorily employed in cobalt-catalyzed aminations. Finally, aminothiophenes were involved in copper-catalyzed mono- and di-N-arylations, affording differently substituted di- and triphenylamines.

This work first discloses a new strategy for amine activation to give reactive amine anion by in situ generated iminium cation-amine anion pair through decomposition of sterically hindered aminals. Utilizing this strategy, a highly regio- and chemoselective cyclocarboamination of ortho-formyl phenylacetylenes with secondary amines has been realized under metal-free mild reaction conditions. The cyclocarboamination with notably tunable product profiles depends on the separation and purification procedure, a diverse range of 1, 3-diamino-1H-indenes (essentially reactive enamines) and 3-amino-1-indanones were obtained, respectively. Moreover, using iodine as an electrophile to couple with various ortho-formyl phenylacetylenes and secondary amines, a series of 3-amino-2-iodo-1-indanones were efficiently achieved with four bonds (C=O, C-C, C-N and C-I) formation in an one-pot three-component reaction. These results demonstrated an unprecedented methodology for the construction of highly functionalized 1H-indene and 1-indanone compounds.
