Multicomponent Synthesis of Dihydropyrimidines and Thiazines

Chemistry – A European Journal, 2006
AbstractA broad range of differently substituted dihydropyrimidines and thiazines can be efficiently prepared by using a four‐component reaction between phosphonates, nitriles, aldehydes, and iso(thio)cyanates. The scope and limitations of this multicomponent reaction are fully described. Variation of all four components has been investigated.

Thiazine, Antibiotic, Bilirubin Adducts

Xenobiotica, 1989
1. Electron charge transfer interactions of some phenothiazine derivatives with aminoglycoside antibiotics, beta-lactams and penicillin-related antibiotics and bilirubin were investigated with alternating current titrations. 2. Neither the beta-lactams nor penicillin-related drugs interacted. 3.

Luminescence of Leuco-Thiazine Dyes

Journal of Fluorescence, 2003
Details of the novel luminescence of the leuco forms of the thiazine dyes, methylene blue and thionine, are reported, including their emission maxima, quantum yields and lifetimes of the luminescence. Other work shows that this luminescence is independent of reducing agent type and solution pH and is a common feature of most thiazine dyes.

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.
