The interplay of conformations and electronic properties in N-aryl phenothiazines

, 2020
A broad series of electronically diverse N-aryl substituted phenothiazines was readily synthesized by Buchwald–Hartwig amination of 10H-phenothiazine and aryl bromides with variable electronic nature in moderate to excellent yields (61–97%). This library

A metal- and oxidizing-reagent-free anodic para-selective amination of anilines with phenothiazines.

Chemical Communications, 2019
A highly para-selective amination of anilines with phenothiazines for producing various functionalized 10-aryl-10H-phenothiazines is reported. The oxidative amination reaction proceeds electrochemically at room temperature, thereby avoiding the use of ...

Phenothiazines and Jaundice§

Australian and New Zealand Journal of Medicine, 1972
Summary: Chlorpromazine and other tranquillizers cause a precipitation of the protein and glycoprotein components of bile in vitro. This precipitation depends on an interaction between the carboxyl groups on the protein and glycoprotein components of bile and the positively charged amine groups on the drug molecules in solution.

Phenothiazin‐Bipyridinium‐Oligooxacyclophane

Angewandte Chemie, 1993
Überraschenderweise zeigt das [11.11]Cyclophan 1(n= 3) in Dichlormethan und Acetonitril transanulare Nuclear‐Overhauser‐Effekte (NOEs) zwischen den Protonen der Bipyridinium‐ und denen der Phenothiazin‐Komponente, was für eine attraktive Donor‐Acceptor‐Wechselwirkung spricht. Durch Komplexierung mit Barium‐Ionen kommen sich auch im [20.20]Cyclophan1(n=
