Technology Process of BROWNIINE

There total 1 articles about BROWNIINE 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: 99.0%

Browniine perchlorate (5005-20-9) → Browniine (5140-42-1)

Guidance literature:

With sodium hydroxide; In methanol;

DOI:10.1021/jo00329a028

Reference yield: 61.0%

(S)-2-Methylbutyric acid (1730-91-2) + Browniine (5140-42-1) → S-(+)-14-(2-Methylbutyryl)browniine, Glaucedine (78039-66-4)

Guidance literature:

With 2,4-diaminopyrimidine; dicyclohexyl-carbodiimide; In dichloromethane; for 20h; Heating;

DOI:10.1021/jo00329a028

Reference yield:

browniine (5140-42-1) + methyl iodide (74-88-4) → delphatine (25488-62-4)

Guidance literature:

With sodium hydride;

DOI:10.1021/ja00411a062

upstream raw materials:
