Zinc-promoted Reactions of (2Z,E)-[2-Aryl(hetaryl)methylidene]-4-chloro-5-phenyl(2,4,6-trimethoxyphenyl)cyclopent-4-ene-1,3-diones with Methyl Bromoacetate.
The reaction of (2Z,E)-[2-aryl(hetaryl)methylidene]-4-chloro-5-phenyl(2,4,6-trimethoxyphenyl)cyclopent-4-ene-1,3-diones with methyl bromoacetate under Reformatsky reaction conditions gave methyl {(5E,Z)-1-hydroxy-2-phenyl-3-chloro-4-oxo-5-[aryl(hetaryl)methylidene]cyclopent-2-en-1-yl}acetates.
