Cyclosulfenylation of 3-allylthiohydantoin

Abstract: Реакцією циклосульфенілювання 3-алілтіогідантоїну у високополярному нітрометані в присутності еквімолярної кількості літію перхлорату як допінг-добавки синтезовані нові конденсовані похідні-перхлорати 2-(арилсульфанілметил)-2,3,5,6-тетрагідроімідазо[2,1-b][1,3]тіазол-7-онію. Їх структура надійно доведена спектральними характеристиками. Зокрема, анелювання тетрагідротіазолонієвого циклу підтверджується наявністю в спектрах ЯМР 1 Н мультиплетних сигналів діастереотопних протонів метиленової групи в положенні С 3… Show more

“…This is favored by the search for new variants of this reaction with still insufficiently studied functional groups of unsaturated compounds and the involvement of new electrophilic reagents. Recently, special attention is paid by the researchers to the reactions of electrophilic intramolecular heterocyclization of alkenyl-and alkynyl-substituted heterocycles [9][10][11]. The development of the synthesis methods for pyrimidine-based heterocyclic systems via its alkenyl derivatives intramolecular cyclization is of practical importance.…”
