N-[bis(methylthio)methylene]amino Ester (BMMA): Novel Reagents for Annelation of Pyrimidine Moieties
摘要:
New reagents for heterocyclic annelations containing a N-[bis(methylthio)methylene]amino moiety (=BMMA) were developed and studied regarding their scope and limitations: one-pot reaction with (hetero)aromatic ortho-aminocarbonyl-type model compounds (''carbonyl'' = COOEt, COMe and CN) to a series of new benzo- or thieno-condensed pyrimidines, pyrrolo[1,2-c]pyrimidines, imidazo[1,2-c]pyrimidines and 1,2,4-triazolo[1,5-c]pyrimidines, depending on the reagent used [(MeS)(2)C=N-R with R = CH2-COOEt, CH(2)CH(2)COOEt, NH-COOEt].

The efficient one-pot synthesis of several newtricyclic systems of type 1 and 2, obtained from the reaction of substituted 2-amino-3-cyanopyrroles and 3-amino-4-cyanopyrroles with BMMAs, is reported. The duration and yields of the reaction strongly depend on the reactivity of the starting pyrrole and on the size of the ring to be formed. Mechanist features of the reaction were investigated and proposed

New pentacyclic heterocycles of the type 3a-e -5a-e were synthesized by one pot reaction of the amino-cyano pyrano[3,2-h]quinolines la-e with BMMAs (e.g. Ethyl N-[bis ( methylsulfanyl) methylene] glycinate, ethyl 2[bis (methylsulfanyl) methylene]-1-methylhydrazine carboxylate and / or ethyl N[ bis( methylsulfanyl) methylene]ß-alaninate). All the synthesized derivatives were identified by conventional
