A green and environmentally friendly cascade reaction of diethyl (2-phenylacetyl)phosphonate with benzylidenemalononitrile promoted by Zr-Ce-SBA-15-NH2 in water was developed, and a wide range of highly functionalized 4H-pyrans containing phosphonate motif were obtained in up to 89% yield. Moreover, SBA-15-NH2 also showed good catalytic activity for this transformation in acetonitrile.
