摘要

The microwave-assisted Wolff rearrangement of cyclic 2-diazo-1, 3-diketones in the presence of aldehydes and primary amines provides a straightforward access to functionalized bi-and pentacyclic oxazinones following an unprecedented three-component domino reaction. Alternatively, in the presence of acyl azides, an efficient Curtius/Wolff/hetero-Diels− Alder sequence allows the direct synthesis of oxazindiones.
