  ABSTRACT A new reagent, tert-butyl (2,4-dioxo-3-azaspiro [5,5] undecan-3-yl) carbonate (Boc-OASUD) for the preparation of N-Boc-amino acids is described. The Boc-OASUD reacts with amino acids and their esters at room temperature in the presence of a base and gives N-Boc-amino acids and their esters in good yields and purity. Introduction of the Boc group takes place without racemization. The Boc-OASUD

  摘要描述了一种用于制备 N-Boc-氨基酸的新试剂叔丁基 (2,4-dioxo-3-azaspiro [5,5] undecan-3-yl) 碳酸酯 (Boc-OASUD)。Boc-OASUD 在室温下在碱存在下与氨基酸及其酯反应，并以良好的产率和纯度得到 N-Boc-氨基酸及其酯。Boc 基团的引入无需外消旋化。Boc-OASUD 是一种固体且更稳定，是二碳酸二叔丁酯的更好替代品，二碳酸二叔丁酯熔点低，由于稳定​​性差，必须在塑料容器中分配，而不是玻璃。图形概要

  A short synthesis of the novel antibiotic aranorosin is described which employs a novel hypervalent iodine-mediated oxidative hydroxylation of a tyrosinal derivative in the key step. A similar procedure was employed to prepare 6′-epiaranorosin, and hence establish the stereochemistry of the natural compound.

• Indium(III) Halides as New and Highly Efficient Catalysts for <i>N</i>-<i>tert</i>-Butoxycarbonylation of Amines
  作者：Asit Chakraborti、Sunay Chankeshwara

  DOI：10.1055/s-2006-942492

  日期：2006.8

  Indium(III) bromide and chloride efficiently catalysed the N-tert-butoxycarbonylation of amines with (Boc)2O at room temperature and under solvent-free conditions. Various aromatic, heteroaromatic and aliphatic amines were converted to N-tert-butylcarbamates in excellent yields in short times. Chiral amines, esters of α-amino acids and β-amino alcohols afforded optically pure N-t-Boc derivatives in high yields. The reactions were chemoselective and no competitive side reactions such as isocyanate, urea, and N,N-di-t-Boc formation were observed. Chemoselective conversion to N-tert-butylcarbamates took place with amino alcohols without any formation of oxazolidinones.

  溴化铟(III)和氯化铟(III)在室温下以及无溶剂条件下有效地催化胺类与(Boc)2O的N-叔丁氧羰基化反应。多种芳香、杂芳香和脂肪胺类在短时间内高效转化为N-叔丁基氨基甲酸酯。手性胺、α-氨基酸酯和β-氨基醇在较高产率下得到光学纯的N-t-Boc衍生物。反应具有化学选择性，未观察到异氰酸酯、脲和N,N-二-t-Boc形成等竞争性副反应。氨基醇也能进行化学选择性转化为N-叔丁基氨基甲酸酯，而不形成噁唑烷酮。
• Novel Non-Peptide GPIIb/IIIa Antagonists. Synthesis and Biological Activities of 2-[4-[2-(4-Amidinobenzoylamino)-2-(substituted)acetyl]-3-(2-methoxy-2-oxoethyl)-2-oxopiperazinyl] acetic Acids.

  To improve the in vitro and in vivo potency of our first low molecular weight GPIIb/IIIa antagonist 1 (TAK-029), a series of 2-[4-[2-(4-amidinobenzoylamino)-2-(substituted)acetyl]-3-(2-methoxy-2-oxoethyl)-2-oxopiperazinyl]acetic acids were synthesized through modification of the glycine moiety of 1 and evaluated for their ability to inhibit in vitro adenosine 5'-diphosphate (ADP)-induced platelet aggregation of guinea pig platelet rich plasma (PRP). Among the compounds examined, the (3S, 2S)-4-methoxyphenylalanine derivative 4h showed the most potent antagonistic activity with an IC50 value of 13 nM. Dose-dependent inhibition of ex vivo platelet aggregation was achieved with oral administration of 4h (0.3-1.0 mg/kg) to guinea pigs. Complete inhibition was observed for up to 8 h, and 43% inhibition could still be observed 24 h after oral administration of 1.0 mg/kg. The long-lasting antiplatelet effect of 4h suggests that 4h would be suitable for once-a-day dosing. Structure-activity relationships (SAR) were examined in the series of the phenylalanine derivatives. An increase in the electron density around the 4-position of the phenyl ring of the phenylalanine moiety led to an increase in the antiplatelet activity, suggesting the existence of a hydrophobic and electrostatic interaction site in addition to the ionic binding sites in the GPIIb/IIIa.

  为了提高我们首个低分子量GPIIb/IIIa拮抗剂1（TAK-029）的体外和体内活性，通过改造1的甘氨酸部分，合成了一系列2-[4-[2-(4-脒基苯甲酰氨基)-2-(取代)乙酰基]-3-(2-甲氧基-2-氧代乙基)-2-氧代哌嗪基]乙酸，并评估了它们抑制体外腺苷5'-二磷酸（ADP）诱导的豚鼠富含血小板血浆（PRP）聚集的能力。在所研究的化合物中，（3S，2S）-4-甲氧基苯丙氨酸衍生物4h显示出最强的拮抗活性，IC50值为13 nM。通过口服给药4h（0.3-1.0 mg/kg）给豚鼠，实现了对体外血小板聚集的剂量依赖性抑制。完全抑制可持续长达8小时，并且在口服1.0 mg/kg后24小时仍可观察到43%的抑制效果。4h的持久抗血小板效应表明4h适合每日一次给药。在苯丙氨酸衍生物系列中考察了构效关系（SAR）。苯丙氨酸部分苯环4位周围的电子密度增加导致抗血小板活性增强，这表明除了离子结合位点外，GPIIb/IIIa还存在一个疏水性和静电相互作用位点。
