Synthesis and reductive cleavage of 3-(2-flurophenyl) and 3-(4-flurophenyl)-cyclopent-5-en[d]isoxazolines by raney nickel in trifluroacetic acid [PDF]

open access: yes, 2013
3-Fluoro arylcycloopent-5-en[d]isoxazolines have been obtained via the 1,3-dipolar cycloaddition of cyclopentadiene to aromatic nitrile oxides. The reductive cleavage of these isoxazolines by Raney nickel in trifluoroacetic acid led to corresponding ...

Synthesis and late-stage functionalization of complex molecules through C-H fluorination and nucleophilic aromatic substitution. [PDF]

open access: yes, 2014
We report the late-stage functionalization of multisubstituted pyridines and diazines at the position α to nitrogen. By this process, a series of functional groups and substituents bound to the ring through nitrogen, oxygen, sulfur, or carbon are ...
