Abstract
A new method has been found for generation of nitrile oxides in situ from nitroalkanes under mild conditions. Thus, reaction of nitroalkanes 1 with di-tert-butyl dicarbonate (2) and 4-dimethylaminopyridine (3) as catalyst in the presence of dipolarophiles at room temperature afforded cycloadducts (e.g. 5, 6, and 7) in improved yields compared to known methods. Solvent effects were also noted.
