Technology Process of chelidamic acid

There total 1 articles about chelidamic acid which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield:

pyridin-4-ol (626-64-2,157061-69-3) + carbon dioxide (124-38-9,18923-20-1) → chelidamic acid (89677-98-5) + 4-hydroxynicotinic acid (609-70-1)

Guidance literature:

With potassium carbonate; at 240 ℃; under 36775.4 Torr;

Reference yield: 70.0%

chelidamic acid (89677-98-5) + ethanol (64-17-5) → 4-hydroxypyridine-2,6-dicarboxylic acid diethylester (68631-52-7)

Guidance literature:

In ethanol; at 80 ℃; for 6h;

DOI:10.1039/c2cc36808k

Reference yield:

chelidamic acid (89677-98-5) → 4-(benzyloxy)-2,6-bis(chloromethyl)pyridine (171000-40-1)

Guidance literature:

Multi-step reaction with 4 steps

1: ethanol / 6 h / 80 °C

2: potassium carbonate / acetonitrile / 12 h / 82 °C / Inert atmosphere
