Substituted oxindoles. Part V. Synthesis and stereochemistry of some substituted 3-benzylidene-1-methylindol-2(3H)-ones
Abstract
1-Methylindol-2(3H)-one was condensed with various substituted benzaldehydes to yield the expected cis/trans condensation products together with some of the corresponding bis-1-methyl-2-oxoindol-3-yl(phenyl)methanes.
