Synthesis of new DOPA derivative from l-tyrosine for construction of bioactive compound

A practical synthetic method of new DOPA derivative was developed with L-tyrosine as starting material. The new DOPA analogue could be used in building bioactive compounds.

Effective syntheses of quinoline-7,8-diol, 5-amino-L-DOPA, and 3-(7,8-dihydroxyquinolin-5-yl)-L-alanine

A modification of the Baeyer-Villiger reaction allows the conversion of aromatic 2-hydroxy-3-nitroketones and aldehydes into 3-nitrocatechols, which can be reduced to 3-aminocatechols. Reaction of the latter with acrolein yields quinoline-7,8-diols under exceptionally mild conditions. This new reaction sequence was successfully applied to the synthesis of the title compounds.
