摘要

本报告介绍了一种制备 3-hydroxy-4-methoxypicolinic acid（具有杀真菌活性的天然产物 UK-2A 的酸基）的新方法。与之前报道的以 3-hydroxypyridine 和糠醛为起始原料制备 UK-2A 酸的两种方法不同，这种新型合成方法采用麦芽酚作为廉价的起始原料，并通过对 Pummerer 反应的独特改良进行。

A New Synthesis of UK-2A Acid Facilitated by a Triple Chloro-Pummerer Activation

A new method for the preparation of 3-hydroxy-4-methoxypicolinic acid, the acid moiety of the fungicidally active natural product UK-2A is reported. In contrast to the two previously reported routes to UK-2A acid, which start from 3-hydroxypyridine and furfural, this novel synthesis applies maltol as inexpensive starting material and proceeds via a unique modification of the Pummerer reaction.
