摘要:Synthesis of the novel compound 3 (3-(5-substituted Oxy-2,4-dinitro-phenyl)-2-oxo-propionic acid ester) to make Pyrroloquinoline quinone (PQQ) and using it for pharmaceutical purposes is described. More specifically, this disclosure relates to synthesizing the PQQ in an efficient method by using a novel intermediate Formula 1 resulting in a shorter process and higher yield of PQQ. A unique process to make sodium compound of PQQ using either sodium hydroxide and/or sodium carbonate is also shown.
