Catalyst free cyclocondensation of β-ethylthio-β-indolyl-α,β-unsaturated ketones with hydrazines has been developed, and 3-pyrazolyl indoles were efficiently synthesized in excellent yields. The catalyst free protocol avoids the use of a large excess of catalysts such as acids and bases, eliminating the discharge of harmful chemicals.
