2,4-Polybenzoxazoles are synthesized from a biosynthetically prepared AB monomer. The biosynthetically produced precursor, 2,3-dihydro-3- hydroxyanthranilic acid (DHAA), is chemically transformed to the AB monomer, 3-hydroxyanthranilic acid (HAA). This AB monomer is used to prepare said polybenzoxazoles.
2,4-聚苯并恶唑是由生物合成制备的 AB 单体合成的。生物合成的前体 2,3-二氢-3-羟基anthranilic acid (DHAA) 通过化学反应转化为 AB 单体 3-hydroxyanthranilic acid (HAA)。这种 AB 单体用于制备上述聚苯并恶唑。
