  • Aryl Radical Cyclizations:  One-Pot Syntheses of Protoberberine and Pavine Alkaloids
    作者:Kazuhiko Orito、Yoshitaka Satoh、Hidetoshi Nishizawa、Rika Harada、Masao Tokuda
    DOI:10.1021/ol006213a
    日期:2000.8.1
    2-(2'-bromo-beta-phenethyl)isoquinolinium bromides 6 and their nor- and homoanalogues (10,11) induced 6-, 5-, and 7-exo radical closures in a one-pot manner to give protoberberines 2, dibenzo[b,g]indolizidine 14a and, dibenzo[a, h]-1-azabicyclo[5.4.0]undecane 15a, respectively. A one-pot radical cyclization of 1-(2'-bromobenzyl)isoquinoline methiodide 18a gave a pavine alkaloid, (+/-)-algemonine (19a).
    在沸腾的苯中用AIBN-Bu(3)SnH处理2-(2'-溴-β-苯乙基)异咔唑7,得到的8-氧代丁苯橡胶3的收率很高。对2-(2'-溴-β-苯乙基)溴化异喹啉鎓6及其正和类似物(10,11)的类似处理以一锅方式诱导6-,5-和7-exo自由基封闭分别得到原小ber碱2,二苯并[b,g]吲哚唑烷14a和二苯并[a,h] -1-氮杂双环[5.4.0]十一烷15a。一锅法将1-(2'-溴苄基)异喹啉甲硫醇18a进行自由基环化,得到了一种牛类生物碱(+/-)-金刚烷(19a)。

    5, 8-Isopuinolinediones (12, 18, 25), 7, 8-isoquinolinediones (14, 19) and 5, 6-isoquinolinediones (26) were synthesized by oxidative demethylation of the corresponding dimethoxyisoquinolines with cerium(IV) ammonium nitrate or silver(II) oxide. 8-Dialkylamino-5, 6-isoquinolinediones (31) and 3, 5-bis(dialkylamino)-7, 8-isoquinolinediones (33) were prepared by copper(II)-catalyzed oxidation of the corresponding isoquinolinols with secondary amines. 5, 8-Isoquinolinediones (29, 34, 40) were also prepared.

  • Gastric-Mucous Membrane Protection Activity of Coptisine Derivatives.
    作者:Hiroyuki HIRANO、Eriko OSAWA、Yumiko YAMAOKA、Toshio YOKOI
    DOI:10.1248/bpb.24.1277
    日期:——
    Coptisine and 8-oxocoptisine were isolated as principles of the gastric-mucous membrane protection from Coptidis rhizoma. The two compounds showed stronger activity than cimetidine and sucralfate. We prepared several derivatives having a partial structure of coptisine from commercially available starting materials. The compounds obtained were tested for gastric-mucous membrane protective activity and a correlation between activity and structure was studied. Our results suggest that the partial charge of the catechol skeleton is related to activity.
