Compound with (α--hydroxy) phenylacetic acid derivatives, and based on it, a 5-membered ring lactone two rings fused to the central cyclohexa-1,4-diene core and use thereof

摘要

It is a precursor essential for the synthesis of compounds having a five-membered ring lactone two rings fused to the central cyclohexa-1,4-diene core is represented by the formula as defined in the description of the invention, (α - It is intended to provide a method for preparing it easily and hydroxy) phenyl acetic acid derivatives,. According to the preparation method of the present invention, without a high purity, high yield, and (α--hydroxy) phenylacetic acid derivatives, or use toxic substances, and to produce toxic by-products, can be readily prepared I can be. (Such as a mixture of other fibers thereto and polyester fibers) synthetic fibers common materials, novel compounds some were synthesized using as a precursor of such a (α--hydroxy) phenylacetic acid derivatives, for microfiber particular It can also be used as a colorant thermoplastic resin, color toners, color filters, etc. and also has a leveling robustness, and dye fixing excellent speed Te.
