• A Stereoselective aza-Prins Reaction: Rapid Access to Enantiopure Piperidines and Pipecolic Acids

  aza-Prins reaction is a widely employed and highly efficient method for the preparation of saturated nitrogen-containing heterocycles. Its major drawback has always been a lack of diastereoselectivity and the formation of racemic products. Herein, we address these problems and report, for the first time, the synthesis of both diastereomerically and enantiopure multiply substituted piperidines via the aza-Prins

  氮杂-普林斯反应是制备饱和含氮杂环的一种广泛采用的高效方法。其主要缺点一直是缺乏非对映选择性和外消旋产物的形成。本文中，我们解决了这些问题，并首次报告了通过aza-Prins反应合成非对映异构和对映纯的多取代哌啶的方法。该方法广泛适用于天然产物的合成，并在此以对映纯的胡椒酸衍生物的合成为例。

  The design and development of the first asymmetric aza-silyl-Prins reaction is reported, giving rise to valuable and diverse piperidines and pipecolic acid derivatives in both high yields and as single enantiomers. The creation of a novel chiral auxiliary-homoallylic amine for the aza-silyl-Prins reaction is essential to its success.

  据报道，第一个不对称氮杂-甲硅烷基-Prins反应的设计和开发，以高收率和单一对映异构体的形式产生了有价值且多样的哌啶和哌考酸衍生物。对于氮杂-甲硅烷基-Prins反应而言，新型手性辅助-均烯丙基胺的产生对于其成功是至关重要的。
• Allyl Silane Additions to Highly Electrophilic 5,6-Dihydro-2H-1,4- oxazinones

  Allylsilane addition to the dihydro-2H-1,4-oxazinones, 1, proceeded in moderate to good yields with transdiastereoselectivity. The yield of addition reactions of 5-phenyl-5,6-dihydro-2H-1,4-oxazin-2-one with allylsilanes is improved over the corresponding additions of Grignard reagents to 1 and illustrates a simple path to protected β,β- disubstituted α-amino acids.

• Diastereoselective Allylstannane Additions to (<i>S</i>)-5,6-Dihydro-2<i>H</i>-5-phenyloxazin-2-one. A Concise Synthesis of (<i>S</i>)-β-Methylisoleucine

  DOI：10.1021/ol1001126

  日期：2010.3.19

  The addition of allyl stannanes to (S)-4,5-dihydro-5-phenyl-2H-oxazinone (3) was achieved under Bronsted acid catalysis to give 2-allylmorpholinones with high diastereoselectivity (up to dr 14.2:1). The product of dimethylallyltributylstannane addition to 3 was converted to L-beta-methylisoleucine, an alpha-amino acid residue found in the complex, biologically active marine-derived peptides polytheonamides A and B, and polydiscamides A-C.
