  Highly efficient one-pot synthesis of D-ring chloro-substituted neocryptolepines via a condensation—Pd-catalyzed intramolecular direct arylation strategy

  摘要：

  D-ring chloro-substituted neocryptolepines have been synthesized in excellent yield starting from 3-bromo-2-chloro-1-methylquinolinium triflate via a one-pot condensation Pd-catalyzed intramolecular direct arylation strategy involving chloroanilines. The 3-bromo-2-chloro-1-methylquinolinium triflate was obtained via methylation of commercial 3-bromo-2-chloroquinoline with methyl triflate. (C) 2010 Elsevier Ltd. All rights reserved.

  isolated from traditional African herbal medicine Cryptolepis sanguinolenta, and its broad spectrum of biological activities has been illuminated in past decades. In this study, neocryptolepine and its derivatives (1-49) were designed and synthesized from economical and readily available starting materials. Their structures were confirmed by proton nuclear magnetic resonance, carbon nuclear magnetic resonance

  Neocryptolepine是一种从传统非洲草药Cryptolepis sanguinolenta中分离出来的生物碱，在过去的几十年中，其广泛的生物活性得到了阐明。在这项研究中，从经济且容易获得的原料中设计和合成了新隐油菜籽及其衍生物（1-49）。通过质子核磁共振，碳核磁共振和质谱法证实了它们的结构。筛选了合成的化合物对六种农业上重要的真菌茄根丝枯病菌，灰葡萄孢（B. cinerea），禾谷镰刀菌，冬瓜霉菌，菌核菌和稻瘟病菌的抗真菌特性。体外测定结果表明，化合物5、21、24、35、40、45，47和47对EC值低于1μg/ mL的真菌表现出显着的抗真菌活性。明显地，化合物24显示出对灰葡萄芽孢杆菌的最有效的抑制效力（EC 50 ＝0.07μg/ mL），并且来自体内实验的数据表明，化合物24表现出与阳性对照的鳞茎鳞茎相当的保护活性。初步的机理研究表明，化合物24显示出令人印象深刻的孢子
