摘要：

Furo[3,2-c]quinolin-4(5H)-ones carrying one or more methoxyl group at their 5, 6, or 8 position can be obtained in yields of up to 60% using a one-step procedure involving an unprecedented [2+3] photoaddition between 5-, 7-, or 8-methoxy-4-hydroxyquinolin-2-one and an alkene in the presence of a benzophenone.
