Chemical Research Letters, May 2021. Redox catalysis has been broadly utilized in electrochemical synthesis. The appropriate choice of redox mediator can avoid electrode passivation, which strongly inhibit the efficient activation of substrates. 20277-69-4, Name is Sodium methanesulfinate, molecular formula is CH3NaO2S. In an article, author is Hussen, Abdulkadir Shube,once mentioned of 20277-69-4, Formula: https://www.ambeed.com/products/20277-69-4.html.
Regioselective Synthesis of Functionalized 1,3-Thiazine-4-ones via Multicomponent Click Reaction Approach
Herein, we disclose a synthetic strategy for the preparation of functionalized thiazinones under exceptionally ambient condition via domino multicomponent click reaction. The protocol utilizes readily available starting materials: phenylisothiocyanates, hydrazine monohydrate and diethyl but-2-ynedioate or dimethyl but-2-ynedioate. The reaction condition merely requires mixing of substrates at room temperature without using any catalyst and/or solvent.
