Quinazolinone-Directed C-H Activation: A Novel Strategy for the Acetoxylation-Methoxylation of the Arenes
摘要:
2-Aryl-4-quinazolinones undergo smooth acetoxylation in the presence of 5 mol% Pd(OAc)(2) and a stoichiometric amount of PhI(OAc)(2) via C-H activation to produce the corresponding acetoxy-substituted 4(3H)-quinazolinone derivatives in good yields with high regioselectivity.
