Synthesis of crown ether compounds as potential inhibitors od enzymatic discolouration of foods

The synthesis of the following crown ether containing compounds as potential polyphenol oxidase inhibitors is described: 4´-N(benzo-crown-5)succinic acid (I), 4´-N(benzo-15-crown-5)maleic acid (II), ester of 4´-N(benzo-15-crown-5)bis[4´-N(benzo-15-crown-5)]phthalic acid (III) and complex of benzo-18-crown-6 with 2-propenyl-acrylamide (IV). The complexes of I , II and IV with potassium 2-propenyl- acrylamide are also described.

complexes of crown ethers containing 2-propenyl-acrylates; inhibitors of polyphenol oxidase; synthesis of crown ether amides
