In the reaction of thiazole-2,4-diamines 8 with isothiocyanates 1, 2,4-diaminothiazole-5-carbothioamides 9, 10, 18, and 19 as well as thiazolo[4,5-d]pyrimidine-7(6H)-thiones 21 were formed. The carbothioamides 9, 10, and 18 were transformed by reaction with different types of monofunctional and bifunctional electrophiles into hitherto unknown acceptor-substituted 4,4′-([2,5′-bithiazole]-2′,4′-diyl)bis[morpholines]
在噻唑-2,4-二胺的反应8与异硫氰酸酯1,2,4-二氨基噻唑-5- carbothioamides 9,10,18,和19以及噻唑并[4,5- d ]嘧啶-7(6 ħ)-硫酮21形成。通过与不同类型的单官能和双官能亲电试剂反应,将碳硫酰胺9、10和18转化为迄今未知的受体取代的4,4'-([[2,5'-bithiazole] -2',4'-二基)双[吗啉] 24和29中,2',4'-双(二烷基氨基)[2,5'- bithiazol] -4-(5 ħ) -酮30以及4-取代的2',4'-双(二烷基氨基)-2,5'-联噻唑31。从30和31的新4单-或4,5-二取代的2',4'-双(二烷基氨基)-2,5'-bithiazoles 34,35,38,和39以及5-取代的2',4双(二烷基氨基)[2,5'- bithiazol] -4(5 ħ) -酮33,36,和37制备。
