  An efficient and convergent synthesis of the potent and selective H3 antagonist ABT-239

  摘要：

  An efficient and convergent process for the preparation of a potent and selective H-3 receptor antagonist, ABT-239, 1A was accomplished with an overall yield of 64%. The key step in the synthesis is a Sonogashira coupling/cyclization reaction of 1-but-3-ynyl-2-(R)-methylpyrrolidine (9) with 4'-hydroxy-3'-iodo-biphenyl-4-carbonitrile (3). Additionally, the key amine component 2-(R)-methylpyrrolidine (7) was effectively synthesized from the readily available Boc-L-prolinol with a simple catalytical hydrogenolysis as the key step. This column chromatography-free process is highlighted by several simple work-up and purification procedures and is amendable to the large-scale preparation of 1A. (c) 2006 Elsevier Ltd.

  Selenium promoted synthesis of enantiopure pyrrolidines starting from chiral aminoalcohols

  摘要：

  Starting from commercially available enantiomerically pure aminoalcohols and using simple conversions promoted by organoselenium reagents, several enantiomerically pure substituted pyrrolidines were prepared. After double protections (R)- or (S)-2-phenylglycinols were converted into the beta-amino selenides by displacing the tosyl group with phenyl selenolate anions. The phenylseleno group was then substituted by an allyl group by treatment with allyltributyltin and AIBN. The reaction of these allylic derivatives with electrophilic phenylselenium reagents afforded selenium containing pyrrolidines as the result of a 5-exo-trig cyclization. The pyrrolidine derivatives thus obtained were reductively deselenylated with triphenyltin hydride and AIBN. Moreover, the selenides were converted into the selenones, which easily gave substitution with different nucleophiles. Enantiopure 2,5-pyrrolidines containing azido, methylthio, cyano and iodo groups were thus obtained. (c) 2007 Elsevier Ltd. All rights reserved.

  A unified approach to access Nβ-protected amino alkyl isothiocyanates using Nβ-protected amino alkyl azides through a general strategy of Staudinger/aza-Wittig reaction is described. The type of protocol used to access isothiocyanates depends on the availability of precursors and also, especially in the amino acid chemistry, on the behavior of other labile groups towards the reagents used in the protocols;

  一种统一的方式来访问Ñ β -保护的氨基烷基异硫氰酸酯使用Ñ β描述了通过Staudinger / aza-Wittig反应的一般策略保护的氨基烷基叠氮化物。用于获得异硫氰酸酯的方案的类型取决于前体的可用性，尤其是在氨基酸化学中，还取决于其他不稳定基团对方案中所用试剂的行为。幸运的是，我们并不担心这两个因素，因为通过标准方案可以轻松制备前体叠氮化物，并且本方案可以为访问标题化合物铺平道路，而不会影响Boc，Cbz和Fmoc保护基以及苄基和叔丁基。侧链。本策略消除了使用胺来获得标题化合物的需要，因此，该方法是分步经济的。其他优点包括保留手性，方便处理和易于纯化。还制备了一些迄今未报告的化合物，所有最终化合物均通过IR，质量，旋光度和1 H和13 C NMR研究。
