Abstract

An Au-catalyzed synthesis of fused pyrroloheterocycles from diverse propargyl-substituted heterocycles proceeds via alkyne-vinylidene isomerization with concomitant 1,2-shift of hydrogen, silyl, germyl, and stannyl groups. This method allows for mild and efficient synthesis of diverse C-2 substituted N-heterocycles.
