Substituted 4-Hydroxypyridines

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention provides a new and efficient synthesis process for producing highly substituted 4-hydroxypyridine derivatives. The method uses readily available starting materials (1,3-diketones, ammonia, and carboxylic acid derivatives), reducing the number of synthesis steps compared to previous methods. The resulting substituted pyridines can be further modified and have potential applications in pharmaceuticals, agrochemicals, molecular electronics, and optics.
