  Substituted benzoquinazolinones. Part 1: Synthesis of 6-aminobenzo[h]quinazolinones via Buchwald–Hartwig amination from 6-bromobenzo[h]quinazolinones

  摘要：

  6-(Morpholin-4-yl)benzothlquinazolin-4(3H)-one derivatives 18a,b were prepared under Buchwald-Hartwig conditions by reacting 6-bromobenzo[h]quinazolin-4(3H)-ones 13a,b with morpholine in the presence of a Pd(OAc)(2)/XantPhos system in 1,4-dioxane as solvent. The starting 6-bromobenzo[h] quinazolin-4(3H)-ones 13 were synthesized via condensation of the ethyl 1-amino-4-bromonaphthalene-2-carboxylate (11) with formamide (Niementowski reaction), and then reaction of the obtained benzoquinazolinone 9 with appropriates benzyl bromides. Compound 11 was prepared using a three-step procedure involving (a) metalation of the N-Boc- or N-Piv-protected 1-aminonaphthalenes with t-BuLi, followed by reaction with ethyl chloroformate, (b) bromination of the naphthalene ring of ester 3 using NBS, and next (c) deprotecion of the amine group with TFA or HCI. Biological screening of the potential cytotoxicity of compounds 8, 9, 18b on A549 and HT29 cell lines, as well as on the lymphocytes showed that compound 18b has interesting anticancer activities. The detailed synthesis, spectroscopic data, and biological assays were reported. (C) 2014 Elsevier Ltd. All rights reserved.

  cascade process occurred to give 9-aminonaphtho[2,3-c]furan-1(3H)-ones in good yields. By using this tandem reaction as a key step, a concise and versatile synthetic strategy for the total synthesis of arylnaphthalene lactone lignans has been developed.

  2-炔基苄腈与Reformatsky试剂的串联反应被证明是一种针对1-氨基萘-2-羧酸酯的新颖而有效的方法。有趣的是，以2-（3-羟基丙-1-炔基）苄腈为底物，发生了更复杂的级联过程，以高收率得到了9-氨基萘[2,3-c]呋喃-1（3H）-。通过将该串联反应用作关键步骤，已开发出用于全合成芳基萘内酯木脂素的简洁而通用的合成策略。

• CuCN-Mediated Cascade Cyclization of 4-(2-Bromophenyl)-2-butenoates: A High-Yield Synthesis of Substituted Naphthalene Amino Esters
  作者：R. Santhosh Reddy、Pragati K Prasad、Brij Bhushan Ahuja、Arumugam Sudalai

  DOI：10.1021/jo400244h

  日期：2013.5.17

  A new method of CuCN-mediated one-pot cyclization of 4-(2-bromophenyl)-2-butenoates leading to efficient synthesis of substituted naphthalene amino esters including phenanthrene aromatic structural units is described. Deuterium labeling studies establish that this one-pot cascade cyclization proceeds through isomerization of olefin, intramolecular C-C bond cyclization, and aromatization as the key intermediates, all occurring in a single step.
