Optically active dipyrrinone sulfide 2 and its sulfoxide 1 have been synthesized as potential precursors to tetrapyrrole analogs of bilirubin with sulfoxide groups replacing the natural carboxylic acids. Dipyrrinones 1 and 2 show weak exciton coupling in their circular dichroism spectra, with Δε427max −0.44, Δε398max +0.50 from 1, and Δε442max –0.67, Δε404max +1.20 from 2, but no evidence for inter-
光学活性的二吡啶酮硫化物2及其亚砜1已被合成为胆红素四吡咯类似物的潜在前体,其中亚砜基取代了天然羧酸。Dipyrrinones 1和2示出弱激子耦合在它们的圆二色光谱,与Δ ε 427最大-0.44,Δ ε 398最大值从0.50 1,和Δ ε 442最大-0.67,Δ ε 404最大1.20从2,但没有证据表明二吡啶酮NHs与亚砜基1之间存在分子间或分子内氢键。
