Total synthesis of LL-Z1640-2 utilizing a late-stage intramolecular Nozaki–Hiyama–Kishi reaction
摘要:
A total synthesis of LL-Z1640-2 (2), a potent and selective kinase inhibitor, has been completed. The key step of the convergent synthesis utilized a late-stage intramolecular Nozaki-Hiyama-Kishi (NHK) reaction to close the macrocycle at the C6'-C7' bond. Published by Elsevier Ltd.

The present invention provides compounds having formula (I), and additionally provides methods for the synthesis thereof and methods for the use thereof in the treatment of various disorders including inflammatory or autoimmune disorders, and disorders involving malignancy or increased angiogenesis, wherein R1 -R11, t, X, Y, Z, and n are as defined herein.
With bioactivity-guided phenotype screenings, a potent anti-inflammatory compound f152A1 has been isolated, characterized and identified as the known natural product LL-Z1640-2. Metabolic instability precluded its use for the study on animal disease models. Via total synthesis, a potent, metabolicallystabilized analog ER-803064 has been created; addition of the (S)-Me group at C4 onto f152A1 has resulted

This work describes the asymmetric synthesis of an aromatic analogue of lipoxin B4 containing a conformationally rigid and potentially more metabolically resistant bicyclo[1.1.1]pentane (BCP) ring incorporated into the upper alkyl chain. This was achieved via the design of a key BCP-containing fragment that could be used as a common intermediate in the synthesis of the target analogue as well as other
这项工作描述了脂氧素 B 4 的芳香族类似物的不对称合成,该类似物包含构象刚性且可能更具代谢耐受性的双环[1.1.1]戊烷 (BCP) 环并入上部烷基链中。这是通过设计一个包含 BCP 的关键片段来实现的,该片段可用作合成目标类似物以及其他杂芳族同系物的通用中间体。
