The preparation of sixteen 3-substituted indoles in good to excellent yields under environmentally friendly conditions has been achieved via a three-component reaction in water of an indole, an aldehyde and malononitrile (or ethyl 2-cyanoacetate) catalysed by 5 mol% of 2-pyrrolecarbaldiminato-Cu(II).
