Benzo[b]thiophene Fusion Enhances Local Borepin Aromaticity in Polycyclic Heteroaromatic Compounds

This report documents the synthesis, characterization, and computational evaluation of two isomeric borepin-containing polycyclic aromatics. The syntheses of these two isomers involved symmetrical disubstituted alkynes that were reduced to Z-olefins followed by borepin formation either through an isolable stannocycle intermediate or directly from the alkene via the trapping of a transient dilithio intermediate. Comparisons of their magnetic, crystallographic, and computational characterization to literature compounds gave valuable insights about the aromaticity of these symmetrically fused [b,f]borepins. The fusion of benzo[b]thiophene units to the central borepin cores forced a high degree of local aromaticity within the borepin moieties relative to other known borepin-based polycyclic aromatics. Each isomer had unique electronic responses in the presence of fluoride anions. The experimental data demonstrate that the local borepin rings in these two compounds have a relatively high amount of aromatic character. Results from quantum chemical calculations provide a more comprehensive understanding of local and global aromatic characters of various rings in fused ring systems built upon boron heterocycles.

Elongated phosphoranes by C-C coupling of haloaroylmethylidene-triphenylphosphoranes: Synthesis and applications

Haloaroylmethylidenephosphoranes 3 can be subjected to Pd(o) mediated C-C coupling reactions to yield diaryl-, arylhetaryl-, dihetaryl, arylethenylaryl/hetaryl- and arylethynylaryl/hetaryl-carbonylmethylidenephosphoranes 4-9. Suzuki-Kumada reactions can also be run in a one-step procedure from (haloaroylmethyl)triphenylphosphonium bromides 2. Compounds 4-9 are air-stable phosphoranes which undergo formal Wittig-olefination reactions with aldehydes 10 under benzoic acid catalysis. C-C coupling reaction and Wittig olefination can also be performed in a one-step procedure. Preliminary experiments have been performed to carry out the synthesis on a solid support. Applications to the chain elongation and functionalisation of the chain terminus in a C-7 substituted estra-1,3,5(10)-triene 14 and a C-16 substituted estra-1,3,5(10),6-tetraene 12 are shown.

A Heteroarylamine Library: Indium-Catalyzed Nucleophilic Aromatic Substitution of Alkoxyheteroarenes with Amines

Under indium Lewis acid catalysis, electron-rich five-membered heteroaryl electrophiles fused with/without a benzene ring were found to couple with amines to produce heteroarylamines with broad structural diversity. The heteroarylamine formation proceeds through the cleavage of a heteroaryl?OMe bond by the nucleophilic attack of the amine based on the nucleophilic aromatic substitution (SNAr) reaction. In contrast to the corresponding traditional SNAr amination, the present SNAr-based heteroaryl amination can be performed without relying on both heteroaryl electrophiles with electron-withdrawing groups and nucleophilicity-enhanced metal amides. High compatibility towards the functional groups such as NO2, Br, I, CF3, CN, CO2Et, pyridyl, thiazolyl, C=C, and OH groups was observed, thus showing the practicality and reliability of this method. Mechanistic studies indicated that a carbon?indium bond is likely to be formed on the heteroaryl ring during the process. (Figure presented.).

Aminobenzoannulated hetero- and carbocycles from 2-azahepta-2,4-dien-6- ynyllithium compounds: Scope and limitation of a novel benzoannulation reaction

Deprotonation of the N-benzylhetarylmethanimines 9, 12, 15, and 18 at -78C with subsequent warming to room temperature over 16 hours and treatment with electrophiles furnished polysubstituted aminobenzoannulated heterocycles 19-25 in good to excellent yields. In a similar fashion, the deprotonation of the N-allyl-2-(alk-1-ynyl)phenylmethanimines 26 and 27 led to 2-vinylnaphthalen-1-amines 28 and 29, respectively, in moderate yields. The reaction of N-[(trimethylsilyl)methyl]imine 31 afforded naphthalen-1-amine 33, unsubstituted at the ortho position after removal of the trimethylsilyl group. The deprotonation of imine 34, bearing a trimethylsilyl group on the C?C bond, gave none of expected amines, but the substituted imine 35, whose structure was identified using 2D NMR spectroscopy.

Two new and efficient routes to benzothieno[2?,3?:4,5]pyrrolo[1,2-f]phenanthridines have been developed. Alkynylated benzothiophenes reacted with various anilines to the target compounds in a domino reaction consisting of a C?N coupling-, hydroamination- followed by a final, ring-closing C?H arylation step. Products were isolated in moderate to good yields. (Figure presented.).

Room-temperature hydrodehalogenation of halogenated heteropentalenes with one or two heteroatoms

The pair NaBH4-TMEDA as a hydride source and catalytic PdCl 2(dppf) in THF prove to be an efficient system for the hydrodehalogenation of bromo(chloro)-heteropentalenes with one or two heteroatoms, while Pd(OAc)2/PPh3 is able to reduce reactive haloheteropentalenes, and PdCl2(tbpf) allows the removal of the 2-chlorine from a thiophene ring. The reaction conditions tolerate various functional groups, allowing highly chemoselective reactions in the presence of halide, ester, alkyne, alkene, and nitrile substituents and also showing good efficiency in the regioselective hydrodehalogenation of a variety of polyhalogenated substrates.
