摘要：
Methoxy group at 5- or 6-position of 2(1H)-quinolinones is compatible with the regioselective electrophilic substitution and chain enlargement at the 3-position imposed by the ortho-directed effect of the quinolinone lithium sail. The coordination effect of a methoxy group at the 8-position changes the reaction course, precluding the ortho-directed metallation and enhancing the conjugate addition at the 4-position.
