Herein, we have disclosed a simple, clean and efficient
procedure for the synthesis of bis(indolyl)methanes 3(a-o)
via threeꢀcomponent oneꢀpot condensation reaction of indole

with substituted aldehydes using β-cyclodextrin as
a
supramolecular catalyst in aqueous medium. The synthesized
compounds 3(a-o) were obtained in good yields (80-92 %)
in less reaction time (20-40 min). The high rate of the reac-
tion is due to superiority of hydrophobic binding of β-
cyclodextrin to hydrophobic substituents, which increases
the reactivity of substrates. β-cyclodextrin is biodegradable,
recoverable and purely environmentally benign. This method
has several advantages over existing catalytic protocols as it
is simple and green experimental procedures, use of green
reaction media (water), lower reaction time, high reaction
rate and avoids cumbersome work-up. Furthermore, this
protocol avoids the problems related to use of organic
solvents, high temperatures and liquid acids, and hence
represents an attractive synthetic strategy for the synthesis of
bis(indolyl)methane from an economic and environmental
perspective.
