有机合成的新世纪——有机合成近年进展鉴赏

A New Era for Organic Synthesis——Highlights of the Recent Progress

本文简要介绍了2005年至今有机合成领域的进展。第一部分有机合成方法学的一些新进展中突出介绍了金属参与的有机合成反应、自由基介导的合成反应、“一个反应瓶”内的多步反应以及不对称反应4个方面;第二部分复杂天然产物全合成则以10个分子为例介绍这方面的进展。

The major progress in organic synthesis since 2005 is briefly surveyed in two parts. The first part deals with some of the most impressive advances in the synthetic methodology, which includes： （1） Metal-mediated synthetic reactions, with an emphasis on the olefin metathesis and gold-mediated reactions. （2） Free radical-based organic synthesis. （3） Synthetic transformations performed in a ＂one-pot＂ manner involving either tandem reactions or multicomponent reactions. （4） Asymmetric reactions catalyzed by metal and organo-catalysts. The major advances in total synthesis of some complex natural products with significant biological activities are presented in the second part, with detailed illustrations of 10 selected molecules, including dragmacidin F, abyssomisin C, 11-acetoxy-g-deoxyasbestinin D, pentacycloanammoxic acid, UCS1025A, （ - ）-Merrilactone A, nigellamine A2, （ ＋ ）-saxitoxin, and tamiflu （an artificially designed natural-like molecule）. An array of complicated structures of the natural products synthesized over the last two years are also listed to serve as a convenient lead to the original literature for the prospective interested readers.
