The interplay of conformations and electronic properties in N -aryl phenothiazines
TL;DR: In this paper, 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.

13C NMR analysis of anthraquinones as models for anthracycline Antibiotics
TL;DR: In this article, the effect of substituents OH, OMe, OAc, and COMe on the chemical shifts has been studied for monosubstituted and some 1,5-and 1,8-disubstitized 9,10-AQ compounds.

Bis[1]benzothieno[1,4]thiazines: Planarity, Enhanced Redox Activity and Luminescence by Thieno-Expansion of Phenothiazine
TL;DR: X-ray structure analyses revealed that anti-anti derivatives have an amazingly coplanar structure of the pentacyclic anellated 1,4-thiazine system, emphasizing a structural similarity to heteroacenes.
