资源简介：
The
chiral Co(III)-complex-templated Brønsted acids were found
to be efficient bifunctional phase-transfer catalysts for the highly
enantioselective bromocyclization of protected tryptamines with readily
available N-bromosuccinimide (NBS) under an air atmosphere.
The 3-bromohexahydropyrrolo[2,3-b]indoles, which
are key building blocks of cyclotryptamine alkaloids, were thus obtained
in up to 95% yield and 93.5:6.5 er.
