    An Efficient Method to Construct the A,B-Rings Component toward Total Syntheses of Phycocyanobilin and Its Derivative as a Photoprobe
    摘要:
    通过开发一种新颖且高效的方法构建A、B环部分,成功完成了藻蓝蛋白胆色素及其在D环上具有光反应基团的衍生物的总合成。该方法包括在nBu3P和碱存在下,4-(1-甲氧基乙基或1-托烯乙基)-3-甲基-5-托烯-1,5-二氢-2H-吡咯烷-2-酮与2-呋喃基吡咯衍生物的Wittig型新偶联反应,随后用铝齐聚物还原,并进行酸或碱处理。

    摘要:
    环戊并[b]吡咯在卟啉合成中的效用已被重新研究。通过在氯化锡(IV)存在下将α-未取代的吡咯17d的丙酰氯侧链环化来制备6-氧代环戊[b]吡咯18。随后用硼氢化钠还原得到相应的6-羟基化合物10,并与α-未取代的吡咯11a和11b进行进一步的酸催化缩合,以优异的产率得到了新型的6-吡咯基环戊[b]吡咯22a和22b。尝试制备脱氧叶绿素铁卟啉(DPEP; 2),这是一种广泛的沉积卟啉分子化石,使用三茂铁-a,c-比拉二烯路线从这些二吡咯中间体得到的结果是不成功的。然而,使用麦克唐纳缩合法成功地进行了三种相关的内消旋β-乙基卟啉的合成,收率中等至良好。在中间开链四吡咯的环戊烯环稠合位点保留sp 3杂化碳桥在大环形成过程中似乎至关重要,因为这会减少外围取代基和碳环之间的空间排斥。

  • Bile pigment studies-VII New syntheses of biliverdin-IXα dimethyl ester and two related mono-vinyl-mono-ethyl isomers

    Using the recently developed route through di-t-butyl b-bilene-1,19-dicarboxylates, new syntheses of biliverdin-IXα dimethyl ester (1) and two related mono-vinyl-mono-ethyl isomers (2) and (3), are described. The two dihydro-derivatives of (1) are important in connection with biosynthetic studies of the origin of algal biliproteins.

  • Azulichlorins and Benzocarbachlorins Derived Therefrom

    Acid-catalyzed condensation of azulidipyrrane aldehydes with a dihydrodipyrrin carbaldehyde afforded the first examples of azulichlorins. These macrocyclic products were isolated in a monoprotonated form, and the free bases proved to be somewhat unstable. The monocations were strongly diatropic, and proton NMR spectroscopy showed the internal C-H at ca. -2 ppm. Addition of TFA gave the related dications, but these exhibited significantly reduced aromatic ring currents. Reaction of an azulichlorin with tert-butyl hydroperoxide and KOH in dichloromethane/methanol gave a benzocarbachlorin and two related aldehydes. The UV-vis spectrum for the benzocarbachlorin showed a split Soret band at 414 and 430 nm, together with a strong chlorin like absorption at 684 nm. The proton NMR spectrum indicated that the carbachlorin is strongly aromatic and the internal C-H was observed at -4.64 ppm. Addition of TFA afforded a C-protonated dication with a significantly increased diatropic ring current. The proton NMR spectrum, NICS calculations, and AICD plots indicated that the system favors a 22 pi electron delocalization pathway that runs through the fused benzo unit. Addition of TFA to the benzocarbachlorin aldehydes primarily led to the formation of monocations, and the generation of C-protonated dications was no longer favored due to the presence of electron-withdrawing formyl moieties.

    Reaction of two equivalents of 5-iodo-3,4-dialkylpyrrole, in situ-generated from the corresponding tertiary butyl ester, with 5,5'-diformyldipyrromethane afforded corrole macrocycle in 20% yield. Utilization of readily available tertiary butyl 5-iodo-3,4-dialkylpyrrole-2-carboxylate and 5,5'-diformyldipyrromethane opens a simple route to corrole. (C) 1997 Elsevier Science Ltd.
