Abstract
A number of 7-hydroxycoumarins (5), on treatment with one equivalent of ( E)-methyl 2-{2-[(chloromethyl)phenyl]}-3-methoxyacrylate (6) at 80°C for 6–8 h, afforded ( E)-methyl 2-{2-[(coumarin-7-yloxy)methyl]phenyl}-3-methoxyacrylates (2) in 80–85% yields. The 7-hydroxycoumarins (5) were in turn prepared from resorcinols (3) and substituted ethyl 3-oxopropanoate (4). Subsequently, results of biological activities evaluated in the greenhouse indicated that several of these compounds have good fungicidal activity against cucumber downy mildew (CDM) at 25g ai/ha.
