An ethylenediamine-promoted three-component synthesis of 3-(thiomethyl)indoles from indoles, thiophenols, and paraformaldehyde has been developed. Water is used as the green solvent in a simple and environmentally friendly procedure. Stable and low-toxicity paraformaldehyde is used as a carbon source.

A novel approach to the synthesis of 7-amino-5-aryl-6-cyano-1,5-dihydro-2H-pyrano[2,3-d]pyrimidine-2,4(3H)-diones in aqueous media under ultrasonic irradiation without catalyst is described. This method provides several advantages such as being environmentally friendly, simple work-up procedure and milder condition. In addition, water was chosen as a green solvent.

ZnO nanoparticles as a worthwhile and recyclable catalyst have been used for the one-pot synthesis of 1,8-dioxo-decahydroacridines and 1,8-dioxooctahydro-xanthenes via multi-component reactions under solvent-free conditions. The presented method is mild, environmentally friendly, inexpensive and highly effective to give the products in good to excellent yields.
