Abstract

We demonstrate here the synthesis of octahydroquinazolinone derivatives through one-pot, three-component condensation reactions of various aryl aldehydes, with a dimedone and urea in 50% aqueous hydrotropic solution (Sodium p-Toluene Sulfonate) under microwave irradiation. This method exhibits efficient and environmentally benign methodology with simple reaction workup for the rapid synthesis of library of octahydroquinazolinones. Moreover, the reaction medium can be easily separated from the product and subsequently reused many times. The present method is of great interest in the context of environmentally greener and safer processes.
