Bis-3-(α-bromoethyl)quinoxalin-2-ones with 3-oxapentane or 3,6-dioxaoctane spacer binding two heterocyclic fragments react with thiourea to give the corresponding bis-spirothiazoloquinoxalines, which upon treatment with acetic anhydride can be converted to podands with terminal thiazoloannulated quinoxaline fragments. X-Ray data for 2′-amino-4-ethyl-5-methyl-1,2,3,4,4′,5′-hexahydrospiro[quinoxaline-2,4′-thiazol]-3-one indicate for this compound a potentiality to form clathrate structures with various solvate molecules.
双-3-(α-溴乙基)喹喔啉-2-酮与 3- 氧杂戊烷或 3,6- 二氧杂辛烷间隔物结合的两个杂环片段与硫脲反应,生成相应的双螺噻唑基喹喔啉类化合物,这些化合物经乙酸酐处理后可转化为带有末端噻唑环化喹喔啉片段的荚状化合物。2′-氨基-4-乙基-5-甲基-1,2,3,4,4′,5′-六氢螺[喹喔啉-2,4′-噻唑]-3-酮的 X 射线数据表明,这种化合物具有与各种溶质分子形成凝块结构的潜力。
