Pd(II)‐catalyzed Carbonylative Cyclization of N‐aryl‐2‐aminopyrimidines with Mo(CO)6 As Carbon Monoxide Source
Asian Journal of Organic Chemistry(2021)
Abstract
A convenient and efficient synthetic protocol for the preparation of pyrimidoquinazolinone through Pd(II)‐catalyzed carbonylative cyclization of N‐aryl‐2‐aminopyrimidines with Mo(CO)6 as carbon monoxide source is established. A series of 6H‐pyrimido[2,1‐b]quinazolin‐6‐one derivatives were obtained in good yields. The scale‐up synthesis was investigated.
