Abstract

An environmentally friendly and clean procedure gives octahydroquinazolinones/thiones by a simple Bigi-nelli condensation of urea/thiourea, aromatic aldehydes, and cyclic 1,3-diones in the presence of indi-um(III) trifluoromethanesulfonate (In(OTf)3) in solventless conditions. This method has advantages such as avoidance of the organic solvents, high yield of pure products without any by-product, short reaction times and operational simplicity.(doi: 10.5562/cca2087)
