Regioselective N-allylation and N-cinnamylation of indoles using CuI-exchanged hierarchical nanoporous material
摘要:
Regioselective N-allylation and N-cinnamylation of indoles are achieved using a novel catalyst of Cu-I-exchanged hierarchically architectured nanoporous material (MMZ(Cu)(Y)(I)). The catalyst was characterized by electron microscopy and X-ray methods. Other advantages like functional tolerance, easy separation and reusability of the catalyst are also highlighted.

ne-system -catalyzed isomerization of olefins has been uncovered. An efficient catalytic combination of [Pd(OAc)2]3-boronate-PCy3-enabled olefin isomerization at 80 °C has been investigated. Addition of water to the reaction showed a remarkable improvement and the isomerization occurred at ambient temperature. These catalytic systems function efficiently for the isomerization of functionalized as well

AbstractA simple salt free and selective N‐allylation of indoles with allylic alcohols has been developed. The protocol uses a catalytic amount of a nickel complex generated in situ from Ni(cod)2 and dppf as diphosphine. The use of DMSO as the reaction solvent is crucial to control the regioselectivity of the reaction with the exclusive formation of the N‐allyl product among up to three possible products.
