Preparation method of selenium-containing heterocyclic compounds |
| abstract |
A reaction of azacyclopropane derivative with elemental selenium and TMSCN to construct a selenium-containing heterocycle under metal-free and additive-free conditions is provided. The new strategy features no metal participation, no additive promotion, a wide substrate selection range and a good functional group compatibility, and provides an efficient and green approach to constructing a variety of selenium-containing heterocyclic compounds in a highly concise way. |
