Abstract The behavior of ketoken gem-dithiols towards active methylene and methyl groups resulted in the formation of thiopyrano-dihydrocaumarine derivatives IIIa, b via cyclocondensation reaction between substituted 4-dihydrocyclohexanone Ia, b. N-phenylpyrazoline derivative VI was also formed through reaction of gem-dithiol IV with malonic acid followed by phenyl hydrazine. Pyridopyridazine derivative
摘要 酮基二硫醇对活性亚甲基和甲基的行为导致通过取代的 4-二氢环己酮 Ia、b 之间的环缩合反应形成噻吩并二氢黄豆素衍生物 IIIa、b。N-苯基吡唑啉衍生物VI也通过偕二硫醇IV与丙二酸和苯肼反应形成。还可以合成吡啶并哒嗪衍生物XII。还研究了 XV 中硫酮基团对某些偶极系统的行为,以得到螺产物 XVIII-XX。

New 2-cyclohexenone derivatives were synthesized via the Michael reaction in the presence of potassium carbonate. These derivatives containing the acetyl substituent in position 6 are of special interest due to the ability to form boronchelatecomplexes, 1,3-dioxaborines, possessing luminescence properties. The dependence of the position of the absorption and luminescence absorption band maxima on
