Abstract

A facile, high yielding, and simple method for the synthesis of a library of dihydropyrimidinones (and -thiones) via the one-pot Biginelli reaction of aldehydes is reported. The method employs the Brønsted acidic IL [bmim(SO3H][OTf] or Zn(NTf2)2as catalyst along with the readily available imidazolium-ILs as solvent, and exhibits good potential for the recycling and reuse of the IL solvent.
