simple cascade

Through a single operation, this kind of tandem/ cascade reaction highly efficiently achieves a sequential construction of both carbon-carbon and carbon-heteroatom bonds. These reactions also provide simple, efficient and new approaches for the synthesis of multiply functionalized organic compounds containing carbon-heteroatom functionality.

该反应经一步操作，高效地实现了碳-杂原子键和碳-碳键的有序构建，为合成含杂原子的多官能团化合物提供了简单有效的新途径。
