A new series of 3′-(4-substitutedphenyl)-4′-(4-(methylsulfonyl)phenyl) spiroisoxazoline derivatives containing naphthalenone and chromanonespiro-bridge were synthesized for evaluation as selective cyclooxygenase-2 (COX-2) inhibitors. A synthetic reaction based on the 1,3-dipolar cycloaddition mechanism was used for the regiospecific formation of various spiroisoxazolines. One of the analogs, i.e., compound 7h, as the representative of the series was recrystallized and characterized structurally by single-crystal X-ray diffraction method. Moreover, the 3D structures of the synthesized compounds were docked into the COX-2 binding site to determine their most probable binding modes once the drug-receptor complexes are formed.

Thermal Isomerization of 7,8-Diazabicyclodeca-2,4,7,9-tetraene N-oxide to Benzaldehyde Oxime
Olsen, Henrik
, p. 1921 - 1926 (1982)
Thermal transformation of 7,8-diazabicyclodeca-2,4,7,9-tetraene N-oxide (3) was observed, (Z)-benzaldehyde oxime being the major product, with (E)-benzaldehyde oxime as a minor product.N-Oxide 3 was labeled with deuterium α to the oxidized N-atom.The location of the deuterium label in the thermolysis products fitted one of two reasonable mechanisms.

Amines are among the most fundamental motifs in chemical synthesis, and the introduction of amine building blocks via selective C—C bond cleavage allows the construction of nitrogen compounds from simple hydrocarbons through direct skeleton modification. Herein, we report a novel method for the preparation of anilines from alkylarenes via Schmidt-type rearrangement using redox-active amination reagents, which are easily prepared from hydroxylamine. Primary amines and secondary amines were prepared from corresponding alkylarenes or benzyl alcohols under mild conditions. Good compatibility and valuable applications of the transformation were also displayed.

A visible light mediated stereospecific C(sp2)-H difluoroalkylation of (Z)-aldoximes to (E)-difluoroalkylated ketoximes has been described. In this reaction, (hetero)-aromatic and aliphatic difluoroalkylated ketoximes could be obtained with the retention of the configuration of the starting aldoximes. A preliminary mechanism study showed that a difluoromethyl radicalviaan SET pathway was involved.
