  摘要：

  已经合成了一系列新的2-（苯基烷基）环氧乙烷-2-羧酸，并研究了其对血糖浓度的影响。大多数化合物在禁食大鼠中表现出显着的降血糖活性。结构活性研究表明，苯环上的取代基（如Cl或CF3）和三至五个碳原子的链长是最有效的物质。在这些化合物中，2- [5-（4-氯苯基）戊基]环氧乙烷-2-羧酸乙酯（36）表现出最有利的活性。

  Switchable C–H Functionalization of N-Tosyl Acrylamides with Acryloylsilanes

  摘要：

  A controllable Rh-catalyzed protocol to access alkylation and akenylation-annulation off N-tosyl acrylamide with, acryloyl silane is reported. In contrast to the directing group or catalyst-dependent divergent sp(2) C-H alkylation/alkenylation the instrinsic property of acryloylsilane allows the switchable reaction manifold, thereby affording either alkylation or alkylation Products with slight modification of the reaction conditions.

  An efficient and convenient palladium-catalyzed direct intermolecular silylation of C(sp2)–H bonds by using disilanes as the silicon source with the assistance of a readily removable bidentate directing group is reported. This strategy provided a regio- and stereoselective protocol for exclusive synthesis of Z-vinylsilanes with reasonable to excellent yields and good functional group compatibility

  N-Mercaptoalkanoyl derivatives of sulfur-containing amino acids were synthesized as candidate angiotensin I converting enzyme (ACE) inhibitors. Among them, N-[3-mercapto-2- (4-methoxybenzyl) propanoyl] -S-ethyl-L-cysteine (5d) was found to be the most potent inhibitor of ACE, with an IC50 value of 0.045μM. The maximum hypotensive effect of this compound was almost equal to that of captopril in anesthetized rats.

  A Ni/(S,S)-BDPP-catalyzed intramolecular Heck cyclization of N-(2-iodo-aryl) acrylamide with 2-methyl-2-phenylmalononitrile was developed to give oxindoles with good enantioselectivities. We found that utilizing such an electrophilic cyanation reagent could tackle the deleterious effect of the coordinative cyanide ion in the asymmetric alkene arylcyanation.
