Abstract

Poly(4-vinylpyridine) is reported as a green, efficient and reusable basic catalyst for the synthesis of 3H-thiazoles under one-pot, three component reaction. This simple method produces the products at room temperature in excellent yields (83-97%). Furthermore, this catalyst can be recovered by simple filtration and recycled up to four consecutive runs without any loss of its efficiency.
