    Substituted pyrrole compounds, such as 3-ethyl-4-methyl-5-carbethoxy pyrrole, 2,4-dimethyl-3-acetyl pyrrole and 2-methyl-5-carboxy pyrrole-4-propionic acid diethyl ester, are alkylated in a single step by reaction with an aldehyde or ketone in the presence of both an acid condensing agent such as hydriodic acid and a compatible reducing agent such as metallic zinc or stannous chloride. Suitable carbonyl reactants include formaldehyde, paraldehyde, isobutyraldehyde, acetone, cyclohexanone and methyl-isobutyl ketone. This application is a continuation application of U.S. application Ser. No. 281,624 filed Aug. 18, 1972, now abandoned, which is a continuation-in-part application of U.S. application Ser. No. 832,001, filed June 10, 1969, now abandoned.

  • Total synthesis of symmetric bile pigments: Mesobilirubin-IVα, mesobilirubin-XIIIα and etiobilirubin-IVγ
    作者:Francesc R. Trull、Roger W. Franklin、David A. Lightner

    日期:1987.11
    The unnatural bile pigments mesobilirubin-IVα, mesobilirubin-XIIIα and etiobilirubin-IVγ were synthesized following self-coupling of the pyrromethenones ψ-xanthobilirubic acid methyl ester, xanthobilirubic acid methyl ester and kryptopyrromethenone, respectively.

  • An inexpensive, selective procedure for oxidizing α-methyl to α-formyl pyrroles pavel bobal
    作者:David A. Lightner
    DOI:10.1002/jhet.5570380531
    日期:2001.9
    α-Methylpyrroles are converted to α-formyl by sodium bromate in aqueous methanol in ∼60% yield. Adding 1% ceric ammonium nitrate as a co-oxidant brings the isolated yields of synthetically useful 2-formylpyrroles 2a-d up to ∼70%, or close to those found when using only the considerably more expensive ceric ammonium nitrate as oxidant.
    在含水甲醇中,溴酸钠可将α-甲基吡咯转化为α-甲酰基。加入1%硝酸铈铵作为助氧化剂,可使合成有用的2-甲酰基吡咯2a-d的分离产率提高至约70%,或接近仅使用昂贵得多的硝酸铈铵作为氧化剂时的产率。

  • Stable 4E-dipyrrinones
    作者:Stefan E. Boiadjiev、David A. Lightner
    DOI:10.1016/s0040-4020(99)00617-1
    日期:1999.9
    Dipyrrinones formed by DBU and n-Bu3P-promoted condensation of 5-p-toluene-sulfonylpyrrolinones with pyrrole 2-aldehydes, gave high yields of product with predominantly the E-configuration when the aldehyde had a 5-carboethoxy group. The 4E-dipyrrinones were readily purified by chromatography and were stable in solutions shielded from light. (C) 1999 Elsevier Science Ltd. All rights reserved.
