✦ Synopsis

A new method for the synthesis of maleate(and phthalate )-bridged cyclophanes is described. For example, cyclophanes 4 (or 5) were obtained in 37-55 % yields by treating maleic (or phthalic) anhydride with various benzene dimethanols and reacting the resulting bis-carboxylate salts with various a, ot'dibromoxylenes. A cyclophane containing copolymer of 4 with 1,3-propanedithiol was prepared.

Flavones were prepared using a one-pot procedure starting from the corresponding 2 0 -hydroxyacetophenones. The latter were treated with 3 equiv of aroyl chloride in wet K 2 CO 3 /acetone (1% w/w water) to afford a good yield of flavone and a smaller amount of 3-aroylflavone. Evidence was obtained t
