N‐alkyl aminomalonates undergo a fast and selective intramolecular C→N acylrearrangement reaction in the presence of a strong base, leading to N‐protected glycinates in excellent yield. Moreover, the fact that the reaction proceeds through a nucleophilic enolate intermediate has been used for implementing a tandem rearrangement/alkylation sequence that has been applied to the preparation of synthetically

The rearrangement of sulfamoyl azides under thermal conditions to form a C–C bond while breaking two C–N bonds is reported. Mechanisticstudy shows that this reaction goes through a Curtius-type rearrangement to form a 1,1-diazene, then which rearranges possibly through both a concerted rearrangement process and a stepwise radical process. This rearrangement could be used in the synthesis of complex

A series of 5-[[1-(4'-carboxybenzyl)imidazolyl]methylidene]hydantoins have been prepared and evaluated as in vitro and in vivo angiotensin II (Ang II) antagonists. Variation of substituents on the hydantoin ring leads to potent and selective Ang II antagonists with nanomolar IC50 values at the AT1 receptor and negligible affinity for the AT2 receptor. Preferred substituents include an n-butyl at R1
已经制备了一系列5-[[[1-(4'-羧基苄基)咪唑基]亚甲基]乙内酰脲,并作为体内和体外血管紧张素II(Ang II)拮抗剂进行了评估。乙内酰脲环上取代基的变化导致有效的和选择性的Ang II拮抗剂,在AT1受体具有纳摩尔IC50值,对AT2受体的亲和力可忽略不计。优选的取代基包括在R1上的正丁基和在R2上的烷基或杂芳基甲基取代基。R2取代基的选择部分取决于其log P的计算,因为在CLOGP和AT1结合亲和力之间观察到显着相关性。许多AT1拮抗剂共有的联苯四唑药效基团可以被例如4-碳甲氧基苯基取代基取代,从而在体外和体内产生有效的Ang II拮抗剂。该系列的代表性化合物是57,它在30 mg / kg po下使肾性高血压大鼠的平均动脉血压降低40%,在10 mg / kg po时降低25%。另外,该化合物在缺盐的正常血压猴子模型中有效,在口服10 mg / kg时最大降低血压27%。总之,这些化合物属于一类新的Ang

size. This manuscript, which builds upon our previous work on Successive Ring Expansion (SuRE) methods, details efforts to better define the scope and limitations of these reactions on lactam and β‐ketoester ring systems with respect to ring size and additional functionality. The synthetic results provide clear guidelines as to which substrate classes are more likely to be successful and are supported
