Synthetic Route of 22013-33-8,New Advances in Chemical Research in 2021. The appropriate choice of redox mediator can avoid electrode passivation and overpotential, which strongly inhibit the efficient activation of substrates in electrolysis. 22013-33-8, Name is 2,3-Dihydrobenzo[b][1,4]dioxin-6-amine,introducing its new discovery.
The synthesis of new substituted dioxino[b]- and [c]phenothiazines or acridinones is reported. N-Arylation of [1,4]benzodioxin-6-amine with organolead or organobismuth reagents gave N-aryl-2,3-dihydro-1,4-benzodioxin-6-amine; subsequent Bernthsen thionation led to phenothiazine ring formation, followed by N-acylation. On the other hand [1,4]benzodioxin-6-amine was first N-alkylated and the resulting alkylamines were N-phenylated before Bernthsen thionation to provide the tetracyclic phenothiazines. Alternative arylation with chlorobenzoic acid followed by cyclization under acidic conditions afforded the dioxinoacridinones, which were successfully alkylated.
I am very proud of our efforts over the past few months and hope to 22013-33-8 help many people in the next few years. Synthetic Route of 22013-33-8
