Two alternative directions for thermal transformation of 6-amino-4-oxopyrano[3,4-d] [1,2,3]thiadiazoles 1, leading either to 6-hydroxy-4-oxo-[1,2,3]thiadiazolo[4,5-c]pyridines 2 or 2-cyano-2-(1,2,3-thiadiazol-5-yl)acetamide 4b, were observed. The fir

Reaction of 5-halo-1,2,3-thiadiazoles with arylenediamines as a new approach to tricyclic 1,3,6-thiadiazepines

A multistep reaction of 5-halo-1,2,3-thiadiazoles and 1,2-phenylenediamines provides a new route to fused 1,3,6-thiadiazepines. The overall process consists of the known stepwise formation of 5-[1-(2-aminophenyl)-1,2,3-triazol-5-ylsulfanyl]-1,2,3-thi

Autor: Natalia N. Volkova, V. A. Bakulev, Yu. Yu. Morzherin, Evgeniy V. Tarasov

Publikováno v: Chemistry of Heterocyclic Compounds. 32:971-974

We have obtained a series of 1,2,3-thiadiazolo[5,4-d]pyrimidines by condensation of 5-(R-amino)-substituted-1, 2, 3-thiadiazoie-4-N-R-(thio)carboxamides with ortho esters.

Publikováno v: ChemInform. 31

Novel bistriazolo[1,3,6]thiadiazepine derivatives have been prepared by the base-catalyzed condensation of aromatic and aliphatic 1,2-diamines with 5-chloro-1,2,3-thiadiazoles, via a multistep process which is thought to involve two Dimroth rearrange

Ring opening in di[1,2,3]triazolo-[1,3,6]thiadiazepine and -[3,1,5]benzothiadiazepine in reactions with butyllithium

Autor: Mikhail I. Kodess, Evgeniy V. Tarasov, Wim Dehaen, Vasiliy A. Bakulev, Natalya N. Volkova

Publikováno v: Mendeleev Communications. 12:131-132

Di[1,2,3]triazolo[1,5-a:5',1'-d][3,1,5]benzothiadiazepine treated with butyllithium undergoes ring opening via the thiophilic addition of butyllithium at the C–S bond, whereas 9,10-dihydrodi[1,2,3]triazolo[1,5-b:5',1'-f][1,3,6]thiadiazepine mainly
