Catalytic,
enantioselective hydroacylations of N-allylindole-2-carboxaldehydes
and N-allylpyrrole-2-carboxaldehydes
are reported. In contrast to many alkene hydroacylations that form
six-membered rings, these annulative processes occur in the absence
of ancillary functionality to stabilize the acylrhodium(III) hydride
intermediate. The intramolecular hydroacylation reactions generate
7,8-dihydropyrido[1,2-a]indol-9(6H)ones and 6,7-dihydroindolizin-8(5H)-ones in moderate to high yields with excellent enantioselectivities.
