Abstract
We report herein an efficient and eco-friendly method for a one-pot sequential synthesis of quinazolin-8-ol derivatives. A variety of boronic acids were used for Suzuki–Miyaura coupling with commercially available SiliaCat ® DPP-Pd heterogeneous catalyst. Use of this catalyst ensures minimal leaching of palladium in the product and alleviates the need of further purification. The reaction conditions used in the four synthetic steps were optimized to telescope three intermediates without first requiring their isolation to establish an efficient and eco-friendly one-pot synthesis.
