Zusammenfassung: | A synthetic strategy that efficiently constructs complex molecular diversity in a few steps will always be embraced by organic chemists. Here, we report a cascade reaction of enynones with enaminones
via
carbene insertion and aryl migration to engineer distinctive multisubstituted furans with an all-carbon quaternary center, and could extend the protocol in the same pot towards furano-pyrrole bis-heterocycles. Heterogeneity of this protocol was proved with the upshot of divergent chemical space under a relatively mild reaction environment.
A cascade reaction of enynones with enaminones
via
cyclative coupling to engineer diverse multisubstituted furans and furano-pyrrole bisheterocycles is described and is proposed to involve carbene insertion and C-C migrations to deliver a totally rearranged product. |
