title: DMAP-Catalyzed [2 + 4] Cycloadditions of Allenoates with N-Acyldiazenes: Direct Method to 1,3,4-Oxadiazine Derivatives.
abstract: An efficient DMAP-catalyzed [2 + 4] cycloaddition of allenoates and N-acyldiazenes is reported. The reaction involved embedding three heteroatoms into a six-membered ring and generated 1,3,4-oxadiazine derivatives in moderate to good yields.
