Technology Process of docosanedioic acid mono-tert-butyl ester

There total 5 articles about docosanedioic acid mono-tert-butyl ester 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: 40.0%

2-carboxy-docosanedioic acid 22-tert-butyl ester → docosanedioic acid mono-tert-butyl ester (1642333-05-8)

Guidance literature:

In toluene; at 110 ℃; for 48h;

Reference yield:

docosanedioic acid (505-56-6) + tert-butyl alcohol (75-65-0) → docosanedioic acid mono-tert-butyl ester (1642333-05-8)

Guidance literature:

With dmap; diisopropyl-carbodiimide; In dichloromethane; at 20 ℃;

Reference yield:

eicosanedioic acid mono(1,1-dimethylethyl)ester (683239-16-9) → docosanedioic acid mono-tert-butyl ester (1642333-05-8)

Guidance literature:

Multi-step reaction with 6 steps

1: borane-THF / tetrahydrofuran / 0 - 20 °C / Inert atmosphere
