The stereoselective diazo transfer reaction with oxime ethers offers an efficient route to the corresponding α‐diazo oxime ethers. The utility of these compounds has been demonstrated by the synthesis of highly substituted pyrroles through a [3+2] cycloaddition of α‐oximino carbenoids with enamines (see scheme).
与肟醚的立体选择性重氮转移反应提供了通往相应α-重氮肟醚的有效途径。这些化合物的用途已通过α-肟基类胡萝卜素与烯胺的[3 + 2]环加成反应合成了高度取代的吡咯(参见方案)。
