Preparation and 1-Carbon Homologation of Boronic Ester Substituted Δ2-isoxazolines: The 1,3 Dipolar Cycloaddition of Nitrile Oxides to Vinyl Boronic Esters

Article abstract of DOI:10.1016/S0040-4039(00)60901-2

The dipolar cycloaddition of a variety of nitrile oxides to pinacol vinylboronate (2) is described.In addition, the 1-carbon homologation of the boronic ester substituted Δ²-isoxazolines obtained from the cycloadditions has been carried out emp
