摘要：
Multicomponent reactions between beta-ketoesters and benzaldehydes for the synthesis of 4H-pyran derivatives promoted by niobium pentachloride (NbCl5) were carried out, providing good yields and reasonable reaction times under mild reaction conditions. (C) 2016 Elsevier Ltd. All rights reserved.
