  摘要：

  On the basis of the increase in lipophilicity, novel benzannelated six- and seven-membered derivatives have been synthesized, starting from 2-hydroxybenzyl alcohols, 2-hydroxybenzaldehydes, and catechol. The X-ray structure of (RS)-1-(2,3-dihydro-5H-1,4-benzodioxepin-3-yl)-5-fluorouracil (5) is presented and compared with its conformational analysis at the semiempirical (AM1) and ab initio (6-31G*) levels and NOE effects. A good agreement between both experimental and theoretical data was found showing a chair conformation for the 2,3-dihydro-5H-1,4-dioxepin ring and an axial orientation of the 5-FU moiety on the C3 position. Compounds 5 and (RS)-1-(7methoxy-2,3-dihydro-5H-1,4-benzodioxepin-3-yl)-5-fluorouracil (6) were found to be the most potent inhibitor of MCF-7 cells growth. (RS)1-(2,3-Dihydrobenzoxepin-2-yl)-5-fluorouracil (8) induced apoptosis up to 57.33% of cell population after 24 It. (C) 2003 Elsevier Science Ltd. All fights reserved.

  The reaction between o-(hydroxymethyl)phenoxyacetaldehyde dimethyl acetals, or 3-methoxy-2,3-dihydro-5H-1,4-benzodioxepins with 5-fluorouracil (5-FU), has been studied. The intramolecular cyclization may be explained through a neighboring group attack to give a 2-(5-fluorouracil-1-yl)oxyranium ion that can be attacked by the silylated benzylic hydroxy group to yield the benzannelated seven-membered

  研究了邻-（羟甲基）苯氧基乙醛二甲基乙缩醛或3-甲氧基-2,3-二氢-5 H -1,4-苯并二恶英与5-氟尿嘧啶（5-FU）的反应。分子内环化可以通过相邻基团的进攻得到2-（5-氟尿嘧啶-1-基）氧基铀离子来解释，该离子可以被甲硅烷基化的苄基羟基进攻以产生苯甲酰化的七元O，N-乙缩醛。还报道了大环反式-双（5-FU O，N-缩醛）的形成。这种化合物将人MCF-7乳腺癌细胞阻滞在G o / G 1处细胞周期的阶段。相反，无环硝基O，N-缩醛似乎起5-FU前药的作用，因为它像众所周知的前药Ftorafur一样，将癌细胞阻滞在S期。
