Abstract

The room temperature 1,3-dipolar cycloaddition reactions of the boron azide, Cy2BN3 with the electron-poor acetylenes RCO2C[triple bond, length as m-dash]CCO2R, EtC[triple bond, length as m-dash]CCOMe and HC[triple bond, length as m-dash]CP([double bond, length as m-dash]O)Ph2 afforded new 1,2,3-triazoles. In the case of RCO2C[triple bond, length as m-dash]CCO2R, a new macrocyclic product was isolated with loss of the R group.
