Abstract
The synthesis of asymmetric 2-indolyl-4-methylenepiperidines 8-11 and 14-15 by condensation of an aminoallylsilane with an indole carbaldehy de, followed by intramolecular cyclization of the intermediate, is des cribed. The reactivity of N-(2-hydroxyethyl)indolylpiperidines 9 and 1 4 with K(t)BuO to give indolo[2,3-a]quinolizidines is studied. Some un expected results are obtained due to the influence of the alpha-phenyl ring.
