Abstract
A new general method for the synthesis of substituted and condensed indoles has been developed via heteroaromatic annelation involving base induced conjugate addition-elimination of 1-methylpyrrole-2-acetonitrile to various α-oxoketene acetals followed by cyclization of the resulting adducts in the presence of TsOH in refluxing benzene.
