Quinazolinone-directed C-H activation: A novel strategy for the acetoxylation-methoxylation of the arenes

Reddy, B.V. Subba,Narasimhulu,Umadevi,Yadav

experimental part, p. 1364 - 1370 (2012/07/27)

2-Aryl-4-quinazolinones undergo smooth acetoxylation in the presence of 5 mol% Pd(OAc)and a stoichiometric amount of PhI(OAc)via C-H activation to produce the corresponding acetoxy-substituted 4(3H)-quinazolinone derivatives in good yields with high regioselectivity.
