Abstract A series of [(α-amino) indol-3-yl]-2-methyl-1-propanones and [(α-amino) indol-3-yl] cyclopentylmethanones has been synthesized by a variety of reductive reactions performed on the corresponding series of (α-azido)-indol-3-yl ketones. One of the more interesting reductive procedures involved the palladium-catalyzed decomposition of formic acid with the formation of hydrogen in situ. The (α-azido) ketones were prepared in excellent yield by ...
