  Abstract:  By acylation with alkyl chloroformate 1 of six N(10)-unsubstituted- (2a-c,e,g,h) and two N(10)-methyl substituted- (5a,b) 3-hydroxy-10H-phenothiazine derivatives eight new alkyl-(10H-Phenothiazin-3-yl)-carbonates (4a-c,e,g,h,7a,b) were synthesized. Two carbonates 7e,f were obtained by 5,5-dioxidation with peroxybenzoic acid. The structural assignments were made on the basis of chemical and spectral methods, and by a study of the derivatization effects (acylation, methylation and 5,5-dioxidation effect) on the chemical shifts of the phenothiazine protons.
