REACTIVITY OF N-SUBSTITUTED p-BENZO AND p-NAPHTHOQUINONEIMINE N-OXIDES TOWARD DIPOLAROPHILES [PDF]

Journal of Sciences, Islamic Republic of Iran, 1990
The dipolar cycloaddition reactivity of N-(1-naphthy1)-1,4- benzoquinoneimine N-oxide and N-phenyl-1,4- naphthoquinoneimine Noxide are investigated, The latter gives the expected adducts with common dipolarophiles such as acrylonitryle, methyl ...

Crystal structure of 5-(4-tert-butoxyphenyl)-3-(4-n-octyloxyphenyl)-4,5-dihydroisoxazole

Acta Crystallographica Section E: Crystallographic Communications, 2019
The molecule of the title compound, C27H37NO3, was prepared by [3 + 2] 1,3-dipolar cycloaddition of 4-n-octylphenylnitrile oxide and 4-tert-butoxystyrene, the latter compound being a very useful intermediate to the synthesis of liquid-crystalline ...

Synthesis of Trifluoromethylated Spiroisoxazolones via a [3+2] Cycloaddition of Nitrile Imines and Unsaturated Isoxazolones

Molecules
A strategy for constructing trifluoromethylated spiroisoxazolones has been developed. This approach relies on the 1,3-dipolar cycloaddition of CF3-substituted nitrile imines, generated in situ from trifluoroacetyl hydrazonoyl bromides and K2CO3, with the

Design, Synthesis, enzyme inhibitory activity and molecular docking studies of new 1,2,3-triazole linked nucleobases

Results in Chemistry
Thirteen novel 1,2,3-triazole linked nucleobases (5a-m) were designed and efficiently synthesized as potential human enzyme inhibitors. The target compounds were synthesized by using Copper (I)-catalysed Huisgen-Sharpless-Meldal 1,3-dipolar cycloaddition
