  Picosecond radical kinetics. Rate constants for ring openings of 2-aryl-substituted cyclopropylcarbinyl radicals

  摘要：

  The kinetics of ring openings of a series of eight (trans-2-arylcyclopropyl)methyl radicals (1) were studied by indirect kinetic methods using Barton's PTOC esters as radical precursors and reaction with PhSeH as the competition reaction. The substituents were CF3, F, Me, and OMe located on both the para and meta positions of the aromatic ring. Syntheses of the radical precursors and the products of the radical reactions are described. Kinetics were determined between -43 and 25 degrees C in four cases (CF, and OMe substituents) and at 0 and 25 degrees C in the other four cases. The rate constants at 25 degrees C ranged from 1.0 x 10(11) s(-1) (p-CH3) to 4.1 x 10(11) s(-1) (p-CF,). The relatively large acceleration of the p-CF3 group, ca. 2.5 times as fast as the parent system with Ar = Ph, correlates well with Adam's Delta D substituent parameters but not with other radical substituent parameters. These calibrated radical rearrangements provide a new set of ultrafast reactions that can be applied in mechanistic probe studies.

  含环丙基和甲基的神经元一氧化氮合酶抑制剂

  摘要：

  已经提出神经元一氧化氮合酶抑制剂作为治疗不同类型神经障碍的治疗剂。在顺式-3,4-吡咯烷支架的基础上，一系列反式已经合成了含有-环丙基和甲基的 nNOS 抑制剂。刚性吸电子环丙基环的插入降低了相邻氨基的碱性，这导致这些抑制剂与母体化合物相比的抑制活性降低。尽管如此，在体外酶分析的基础上，其中三个表现出两位数的纳摩尔抑制和高 nNOS 选择性。与这些抑制剂结合的 nNOS 和 eNOS 的晶体结构为详细的构效关系 (SAR) 研究提供了基础。这些研究的结论将用作未来选择性 NOS 抑制剂开发的指南。

  putative A(3)AR binding site around the phenyl moiety. A heteroaromatic group (3-thienyl) could substitute for the phenyl moiety with retention of high affinity of A(3)AR binding. Other related N(6)-substituted adenosine derivatives were included for comparison. Although the N(6)-(2-phenyl-1-cyclopropyl) derivatives were full A(3)AR agonists, several other derivatives had greatly reduced efficacy. N(6)

  We report here the design, synthesis, and pharmacological properties of a series of compounds related to tranylcypromine (9), which itself was discovered as a lead compound in a high-throughput screening campaign. Starting from 9, which shows modest activity as a 5-HT2C agonist, a series of 1-aminomethyl-2-phenylcyclopropanes was investigated as 5-HT2C agonists through iterative structural modifications. Key pharmacophore feature of this new class of ligands is a 2-aminomethyl-trans-cyclopropyl side chain attached to a substituted benzene ring. Among the tested compounds, several were potent and efficacious 5-HT2C receptor agonists with selectivity over both 5-HT2A and 5-HT2B receptors in functional assays. The most promising compound is 37, with 120- and 14-fold selectivity over 5-HT2A and 5-HT2B, respectively (EC50 = 585, 65, and 4.8 nM at the 2A, 2B, and 2C subtypes, respectively). In animal studies, compound 37 (10-60 mg/kg) decreased immobility time in the mouse forced swim test.
• The First Cyclopropanation Reaction of Unmasked α<i>,</i>β-Unsaturated Carboxylic Acids:  Direct and Complete Stereospecific Synthesis of Cyclopropanecarboxylic Acids Promoted by Sm/CHI₃

  DOI：10.1021/ol0709174

  日期：2007.7.1

  A samarium-promoted cyclopropanation of unmasked alpha,beta-unsaturated acids is described. This reaction can be carried out on (E)- or (Z)-alpha,beta-unsaturated carboxylic acids. In all cases the process is completely stereospecific and stereoselective. A mechanism has been proposed to explain the cyclopropanation reaction.
• Silver-Promoted, Palladium-Catalyzed Direct Arylation of Cyclopropanes: Facile Access to Spiro 3,3′-Cyclopropyl Oxindoles

  日期：2013.3.15

  The Pd-catalyzed, Ag(I)-mediated intramolecular direct arylation of cyclopropane C H bonds is described. Various spiro 3,3'-cyclopropyl oxindoles can be obtained in good to excellent yields from easily accessible 2-bromoanilides. The kinetic isotope effect was determined and epimerization studies were conducted, suggesting that the formation of a putative Pd-enolate is not operative and that the reaction proceeds via a C-H arylation pathway.
