  Asymmetric synthesis of ω-bromo-2(S)-azido acids as precursors for the synthesis of novel amino acids

  摘要：

  A series of omega-bromo-2(S)-azido acids with side-chain lengths ranging from 3-5 methylene units has been synthesized. These intermediates enable the facile synthesis of chiral non-natural amino acids containing virtually any nucleophile capable of substituting the omega-bromo group. (C) 1998 Elsevier Science Ltd.

  Conjugates of Modified Cryptophycins and RGD-Peptides Enter Target Cells by Endocytosis

  摘要：

  Tumor targeting anticancer drug conjugates that contain a tumor recognition motif (homing device) are of high current relevance. Cryptophycins, naturally occurring cytotoxic cyclo-depsipeptides, have been modified by total synthesis to provide analogues suitable for conjugation to peptide-based homing devices. An array of functionalized beta(2)-amino acids was synthesized and incorporated into cryptophycins. All analogues proved to be highly active in the cytotoxicity assay using the human cervix carcinoma cell line KB-3-1 and its multidrug-resistant subclone KB-V1. Conformational analysis of cryptophycin-52 and two synthetic analogues was performed by NMR and MD methods to obtain information on the influence of the unit C configuration on the overall conformation. An azide-functionalized cryptophycin was connected by CuAAC to an alkyne-containing fluorescently labeled cyclic RGD-peptide as the homing device for internalization studies. Confocal fluorescence microscopy proved integrin-mediated internalization by endocytosis and final lysosomal localization of the cryptophycin prodrug.

  Abstract A series of ω‐bromo‐2(S)‐methyl acids has been synthesized as precursors of novel arginine (Arg), lysine (Lys), and mercapto analogues. These intermediates contain α‐methyl groups and are designed to mask the N‐terminal amine when incorporated in pharmaceutically relevant peptides.

  The recently reported natural product Sch 382583 (1), an inhibitor of peptide deformylase, has been synthesized in 16 steps from commercially available starting materials. The three chiral centers were set by a combination of chiral auxiliary and chiral pool approaches. The succinate 5 and piperazic acid 9 moieties were obtained by Evans oxazolidinone imide enolate alkylation and hydrazination/cyclization

  最近报道的天然产物Sch 382583（1），一种肽去甲酰基酶的抑制剂，已由市售起始原料分16步合成。三个手性中心是通过手性辅助方法和手性池方法的组合设置的。分别通过伊文思恶唑烷酮酰亚胺烯酸酯烷基化和酰化/环化获得琥珀酸酯5和哌嗪酸9部分，并且通过格氏（Grignard）取代衍生自I的Weinreb酰胺制备氨基己酮侧链13。-缬氨酸。与所报告的天然产物的数据相比，所得合成材料的光谱数据确定了先前未分配的缬氨酸酮立体中心（C-4）具有S-构型。

  and Manaviazar (1992) on the asymmetric synthesis of (3R)- and (3S)-piperazic acids has been reinvestigated, and the originally claimed product yields fully substantiated. The claims made in reference 13 about the proportions of cyclised product 6 and starting bromide 20 isolated from the low temperature electrophilic hydrazination-nucleophilic cyclisation of 20 with di-t-butylazodicarboxylate (DBAD)

  为了回应Decicco和Leathers的最新文献报告（参考文献13），Hale，Delisser和Manaviazar（1992）关于（3 R）-和（3 S）-哌嗪酸的不对称合成的工作已被重新研究。 ，并且最初要求保护的产品的产量得到了充分证实。参考文献13约环化产物的比例制得的权利要求6和起始溴化物20从低温电hydrazination亲核环化分离20与二吨偶氮二羧酸丁酯（DBAD）和DMPU作为添加剂不准确。他们证明，当将DMPU加入到肼化反应混合物中时，逆酰肼化反应是有问题的，已经证明对环化产物的收率没有严重的不利影响并且是不重要的。参考文献13的另一主要主张是，当使用n -Bu 4 NI代替添加剂（代替DMPU）时，20的亲电肼化和亲核环化产生91％的分离产率中的6，这也是错误的。我们仔细地重复了按比例缩小版本的n -Bu 4 NI催化程序（参考资料13），发现经快速色谱分离后，

  日期：——

  A convenient asymmetric synthesis of both (3R)- and (3S)-piperazic acids has been developed that is based on electrophilic hydrazination of a chiral bromovaleryl carboximide enolate with di-tert-butyl azodicarboxylate, followed by subsequent intramolecular SN2 displacement of the bromide by the resulting substituted aza anion. The diastereoselectivity of the process is typically greater than 96%.
