Catalytic, Asymmetric, Interrupted Feist–Bénary Reactions of α-Tosyloxyacetophenones
摘要:
A new variant of the Interrupted Feist-Benary (IFB) reaction uses alpha-tosyloxyacetophenones as electrophiles and proceeds in good yields and excellent enantioselectivities.

A rhodium(III)-catalyzed C–H/N–H bond functionalization for the synthesis of 1-aminoisoquinolines from aryl amidines and α-MsO/TsO/Cl ketones was achieved under mild reaction conditions. Thus, this approach provides a practical method for the site-selective synthesis of various synthetically valuable isoquinolines with wide functional group tolerance.
