1,3-Thiazines

1990
Publisher Summary This chapter discusses the monocyclic thiazines and their functionalized derivatives. The sp 3 -hybridized saturated carbon bearing the extra hydrogen was indicated by a number placed after those for the heteroatoms. Hence, 2H-1,3-thiazine was named 1,3,2-thiazine. The chapter discusses the synthesis of 1,3-thiazines.

Synthesis of 4H-thiazines

Chemistry of Heterocyclic Compounds, 2016
Thiazines represent an important class of heterocyclic compounds due to their valuable biological properties. For example, some derivatives of thiazine are cannabinoid receptor agonists, also they can act as an antihypotensive, antitubercular, and antibacterial agents.

Photo-Sensitivity of Thiazine Leucobases

Nature, 1961
DURING the course of experiments designed to investigate the staining of nucleic acid in histological sections, I happened to gather together on one bench a number of solutions of basic dyes reduced to their colourless sulphite leucobase. These included methyl green, basic fuchsin and a series of thiazines, namely, thionin, azure A, B and C, and ...

N,N-DIALKYLAMINOALKYL SUBSTITUTED QUINOBENZO[1,4]THIAZINES AND DIQUINO[1,4]THIAZINES#

Phosphorus, Sulfur, and Silicon and the Related Elements, 2000
Abstract 12-(N,N-Dialkylaminoalkyl)quino[1,4]benzothiazines 2c-2g were obtained by alkylation of 12H-quino[1,4]benzothiazines 2a and 2b with N,N-dialkylaminoalkyl chlorides in dioxane. 14H-Diquino [1,4]thiazine 4a was unreactive in the same conditions.

Quinoxalino[2,3-b]-1,4-thiazines

Chemistry of Heterocyclic Compounds, 1971
Quinoxalino[2,3-b]-1,4-thiazines were obtained by the reaction of 2-aminoquinoxaline-3-thione and its 6,7-dimethyl derivative with α-halocarbonyl compounds. Hydrolysis of these compounds in alkaline and acid media gave 2-amino-3-quinoxalone and quinoxaline-2,3-dione. The IR and UV spectra are presented.

Dielectric properties of thiazine derivatives

Electrochimica Acta, 1968
Abstract The thiazine derivatives promethazine, chlorpromazine, trimeprazine, prochlorperazine, trifluoperazine, methotrimeprazine and thioproperazine exhibit similar dielectric behaviour, and all except the last two are subject to severe supercooling.
