Synthesis of new heterylmethylidene derivatives of isomeric imidazo[4,5-e]thiazolo-fused [1,2,4]triazines
Novel 6-heterylmethylidene-3a,9a-diphenylimidazo[4,5-e]-thiazolo[3,2-b][1,2,4]triazines were synthesized by the three-component condensation of imidazo[4,5-e][1,2,4]triazine-3-thione derivative with bromoacetic acid and hetero-aromatic aldehydes. The following MeONa-induced skeletal rearrangement gave the recyclized isomeric products, viz. 7-heterylmethylidene-3a,9a-diphenylimidazo-[4,5-e]thi azolo[2,3-c][1,2,4]triazines.
期刊介绍：
Mendeleev Communications is the journal of the Russian Academy of Sciences, launched jointly by the Academy of Sciences of the USSR and the Royal Society of Chemistry (United Kingdom) in 1991. Starting from 1st January 2007, Elsevier is the new publishing partner of Mendeleev Communications.
Mendeleev Communications publishes short communications in chemistry. The journal primarily features papers from the Russian Federation and the other states of the former USSR. However, it also includes papers by authors from other parts of the world. Mendeleev Communications is not a translated journal, but instead is published directly in English. The International Editorial Board is composed of eminent scientists who provide advice on refereeing policy.
