✦ Synopsis

Indoles react with a@unsaturated carbonyl compounds in the presence of clay catalysts to give substituted indoles in good yields; in one case a 3-benzyl substituent already present migrated to the 2-position, being displaced by the incoming electrophile, thus confirming that electrophilic substitution in indole occurs primarily at the 3-position.

a-Acetoxymethylpyrroles couple with a-free pyrroles in presence of Montmorillonite clay to form unsyrmnetrical pyrromethanes in excellent yields. Symmetrical pyrromethanes were also prepared in a similar manner by clay catalysed self-condensation of a-acetoxynmthylpyrroles.
