Herein, a protecting-group-free protocol was developed to realize a time and step economy diversification of the Meridianin alkaloid. A broad range of substituents are tolerated to deliver the products in moderate to high yields, and the first synthesis of Meridianin B was achieved. The simplicity of this protocol enables the rapid construction of a Meridianin derivative library for antibiofilm evaluation
在此,开发了一种无保护基团的方案,以实现 Meridianin 生物碱的时间和步骤经济多样化。广泛的取代基可以以中等到高的产率提供产品,并且实现了 Meridianin B 的首次合成。该协议的简单性使得能够快速构建用于抗生物膜评估的 Meridianin 衍生物库。初步结果表明,经络宁衍生物能够协同抑制鲍曼不动杆菌生物膜并降低抗生素 MIC。

Meridianins, marine alkaloids known as kinase Inhibitors with an indole skeleton, and meridianin analogues were produced regioselectivity and in moderate to good yields by thermal annulation of nitrosoarenes with 2-amino-4-ethynylpyrimidine and 2-chloro-4-ethynylpyrimidine, respectively, through a novel and atom-economical indolization process (C) 2009 Elsevier Ltd All rights reserved
