An etiobilirubin-IIβ analog with the central C(10) CH2 group replaced by a diacetylene unit (1) was synthesized by base-catalyzed condensation of bis-[3-methyl-4-ethyl-5-formylpyrrol-2-yl]-diacetylene (3) with 3-methyl-4-ethyl-5-p-toluenesulfonyl-2-pyrrolinone (10). Diacetylenic rubin 1 is a dark red solid, giving orange solutions with uv-visible absorption maxima near 460 nm.
通过双-[3-甲基-4-乙基-5-甲酰基-吡咯-2-基]的碱催化缩合反应合成了一个中心胆碱(10)CH 2基团被联乙炔单元(1)取代的乙胆红素-IIβ类似物。-二乙炔(3)与3-甲基-4-乙基-5-对甲苯磺酰基-2-吡咯烷酮(10)。二乙炔红蛋白1是深红色固体,产生橙色溶液,在460 nm附近具有uv可见光吸收最大值。
