摘要：

Delta-Alkynyl oximes undergo a concerted 2n + 2pi + 2sigma 1,3-azaprotio cyclotransfer (APT) reaction generating cyclic N-vinyl nitrones which have been trapped in cycloaddition reactions; MNDO and AM1 calculations and transition-state modelling provide support for the observed greater facility of oxime-alkyne reactions compared to oxime-alkene reactions.
