The isomalabaricanes comprise a large family of marine triterpenoids with fascinating structures that have been shown to be selective and potent apoptosis inducers in certain cancer cell lines. In this article, we describe the successful total syntheses of the isomalabaricanes stelletin A, stelletin E, and rhabdastrellic acid A, as well as the development of a general strategy to access other natural
异马拉巴烷包括一大类海洋三萜类化合物,具有迷人的结构,已被证明是某些癌细胞系中选择性和有效的细胞凋亡诱导剂。在这篇文章中,我们描述了异马拉巴烷类 stelletin A、stellin E 和 Rhabdastrellic acid A 的成功全合成,以及开发获取这一独特家族中其他天然产物的一般策略。在这一努力中使用了高通量实验和计算化学方法。对 stelletin A 的初步构效关系研究揭示了异马拉巴烷的 trans-syn-trans 核心基序对其细胞毒活性至关重要。

N-Heterocyclic Carbene Catalyzed Dynamic Kinetic Resolution of Pyranones

DOI:10.1002/anie.201508205
日期:2016.1.26
The dynamickineticresolution of 6‐hydroxypyranones with enals or alkynals through an asymmetric redox esterification is catalyzed by a chiral N‐heterocyclic carbene. The resulting esters are obtained in good to high yields and with high levels of enantio‐ and diastereocontrol. The reaction products are further derivatized to obtain functionalized sugar derivatives and natural products.
Chemoselective formation of cyclo-aliphatic and cyclo-olefinic 1,3-diols <i>via</i> pressure hydrogenation of potentially biobased platform molecules using Knölker-type catalysts

Hemicellulose-derived five-membered cyclic ketones are strategic precursors for sustainable 1,3-diol building blocks, and bifunctional iron catalysts provide unprecedented chemoselectivity in hydrogenation toward aliphatic and olefinic structures.
