Synthesis of Dihydrobenzoheterocycles through Al(OTf)3-Mediated Cascade Cyclization and Ionic Hydrogenation
摘要:
A facile and versatile synthesis of dihydrobenzoheterocycles via Al(OTf)(3)-mediated cascade cyclization and ionic hydrogenation has been developed. The reaction is applicable to a wide range of substrates with various functional groups to afford the corresponding products in good yields.
