Synthesis of 3,4-Dihydro-2H-1,3,5-thiadiazines

, 2016
3,4-Dihydro-2H-1,3,5-thiadiazines substituted at the 3 and 6 positions were synthesized by treatment of N-substituted N,N-bis(1H-1,2,3-benzotriazol-1-ylmethyl)-amines with thioamides and zinc bromide in dry CH2Cl2 at room temperature for 48−60 h in 48−80%

Synthesis and Structure of Novel 1λ⁴,2,6-Thiadiazines

, 2016
S,S-Disubstituted sulfodiimines 9 are known to be versatile building blocks for the synthesis of various sulfur−nitrogen-containing heterocycles. Addition−condensation reactions of 9 with three different activated carbonylsubstrates 14−16 lead to several

Substituted 2-amino-1,3,4-thiadiazines: a novel solid-phase approach

, 2002
A novel and facile strategy for synthesis of substituted 2-amino-1,3,4-thiadiazines on solid support is described. Resin bound isothiocyanate prepared from an immobilised primary amine and di-(2-pyridyl)thionocarbonate was reacted with hydrazine hydrate ...

Synthesis of N‑Aryl-3,5-dichloro‑4H‑1,2,6-thiadiazin-4-imines from 3,4,4,5-Tetrachloro‑4H‑1,2,6-thiadiazine

, 2015
Condensation of 3,4,4,5-tetrachloro-4H-1,2,6-thiadiazine with a range of anilines gave 22 N-aryl-3,5-dichloro-4H-1,2,6-thiadiazin-4-imines in 43–96% yields. The scope and limitations of this condensation are briefly investigated.
