An efficient palladium-catalyzed synthesis of N-functionalized multisubstituted indoles from easily accessible ortho-haloarylallenes and primary amines has been developed. A wide range of electronically and structurally varied nitrogen fragments could be introduced through this tandem C-N bond-forming process by tuning the reaction conditions.

Different from the reaction of 2,3-allenoic acids with Selectfluor, 4-fluoro-2(5H)-furanones and (E)-3-fluoro-4-oxo-2-alkenoates were highly selectively generated from 2,4-disubstituted 2,3-allenoates with Selectfluor under different conditions in moderate yields. The reaction of 2, 4, 4-trisubstituted 2,3-allenoates afforded the corresponding 4-fluoro-2(5H)-furanones highly selectively with up to 95% yield under different conditions. The scope of the substrates has been carefully explored. Due to the more readily availability of 2,3-allenoates as compared to 2,3-allenoic acids, new 4-fluoro-2(5H)furanones were prepared. Based on the isolation and characterization of the minor fluorohydroxylation product E-5m, a mechanism has been proposed. The Royal Society of Chemistry 2010.
