• The coumarin→indole transformation—a method for preparing 4-halo-5-hydroxyindoles from coumarins
  作者：Elia J. L. Stoffman、Derrick. L. J. Clive

  DOI：10.1039/b914580j

  日期：——

  Readily accessible 3-alkoxycarbonyl-6-hydroxy-5-halocoumarins can be converted into 4-halo-5-hydroxyindoles by a sequence whose essential steps are conjugate reduction or conjugate addition, decarboxylation, lactone opening with ammonia, phenolic oxygen protection, Hofmann rearrangement to an N-Boc ethylamine, oxidation to a quinone and deprotection of the nitrogen. The resulting β-aminoethyl quinone cyclizes to a mixture of quinone imine and indole, and the imine tautomerizes to the indole spontaneously or on treatment with rhodium on alumina.

  readily accessible 3-烷氧羧基-6-羟基-5-卤代香豆素可以通过一系列步骤转化为4-卤代-5-羟基吲哚，主要步骤包括共轭还原或共轭加成、脱羧、与氨的内酯开环、酚氧保护、霍夫曼重排为N-Boc乙胺、氧化为醌及氮的去保护。生成的β-氨基乙基醌环化为醌亚胺和吲哚的混合物，亚胺可以自发或在铝土矿上的铑处理下转化为吲哚。

• Studies on quinones. Part 42: Synthesis of furylquinone and hydroquinones with antiproliferative activity against human tumor cell lines

  The preparation of furyl-1,4-quinone and hydroquinones by reaction of 2-furaldehyde N,N-dimethylhydrazone with benzo- and naphthoquinones is reported. Access to furylnaphthoquinones from unactivated quinones requires acid-induced conditions, however oxidative coupling reactions of activated quinones proceed under neutral conditions. The in vitro cytotoxic activity of the prepared compounds against a panel of three human cancer cell lines has been studied. Most of the furyl-1,4-quinones exhibited good antiproliferative activity (GI(50) = 6.5-33.5 mu m) against the MCF-7, NCI-H460, and SF-268 (CNS cancer) cell lines chosen for testing.
