  Highly selective conversion of N-aroyl-α-dehydronaphthylalaninamides into 3,4-dihydrobenzoquinolinone derivatives via photoinduced intermolecular electron transfer

  摘要：

  The irradiation of substituted (Z)-N-aroyl-alpha-dehydronaphthylalaninamides [(Z)-1] in methanol containing triethylamine (TEA) with Pyrex-filtered light was found to give 3,4-dihydrobenzoquinolinone derivatives (2) in high yields along with minor amounts of 4,5-dihydrooxazole derivatives (3). Analysis of the substituent effects on product composition revealed that both the photoreactivity of 1 and the selectivity of 2 are decreased with increasing electron-withdrawing ability of the substituent introduced at the para-position on the N-benzoyl benzene ring. From the analysis of the dependence of the quantum yield for the formation of 2 on the TEA concentration, it was found that back electron transfer occurs efficiently within an (E)-1 anion radical-TEA cation radical pair intermediate.

  Neutral Peptide Biradicals Formed by Dissociative Electron Transfer

  摘要：

  [GRAPHICS]A new method for the generation of transient neutral biradicals in liquid solution is reported. Photoinduced electron transfer in aqueous solution of the structures shown above leads to neutral biradicals with peptide spacers. Exchange interactions were measured using time-resolved electron paramagnetic resonance (TREPR) and found to be large for the biradicals possessing two and three glycine residue spacers, These findings are compared to previous results from alkyl spaced biradicals of similar chain length.

  perfluoroalkyl tags were deposited on fluorous reversed-phase silica 1 and unmodified silica gel. These supported complexes were successfully used as precatalysts for the Suzuki reaction in H2O. H2O-Soluble aryl bromides were easily converted to the corresponding biphenyls. Although none of the complexes is H2O-soluble, the active catalyst is most likely homogeneously dissolved. Nevertheless, the Pd-leaching

  As a continuation of our previous work, a series of new phenyl acrylamide derivatives (4Aa-g, 4Ba-t, 5 and 6a-c) were designed and synthesized as non-nucleoside anti-HBV agents. Among them, compound 4Bs could potently inhibit HBV DNA replication in wild-type and lamivudine (3TC)/entecavir resistant HBV mutant strains with IC50 values of 0.19 and 0.18 μM, respectively. Notably, the selective index value

  作为我们先前工作的延续，设计并合成了一系列新的苯基丙烯酰胺衍生物（4Aa-g，4Ba-t，5和6a-c）作为非核苷类抗HBV剂。其中，化合物4Bs可以有效抑制野生型和拉米夫定（3TC）/恩替卡韦耐药HBV突变株中HBV DNA复制，IC 50值分别为0.19和0.18μM。值得注意的是，4Bs的选择性指数值高于526，表明安全性良好。有趣的是，不像核苷类似物3TC，4BS能显著禁止3.5kb的pgRNA表达。分子对接研究表明4B通过疏水，π-π和H键相互作用可以很好地适合HBV核心蛋白的二聚体-二聚体界面。考虑到强效的抗HBV活性，低毒性以及与核苷类抗HBV药物3TC不同的抗HBV机理，化合物4Bs有望成为开发新型非核苷类抗HBV治疗药物的有希望的线索，并值得进一步研究。

  chiral bisphosphine ligand, was found to be an efficient catalyst for the asymmetric hydrogenation of 2-amidoacrylates, affording the chiral α-amino acid esters in quantitative yields and excellent enantioselectivity (up to 96 % ee). The active catalyst component was studied by NMR and HRMS, which helped us to realize high catalytic efficiency on a gram scale with a low catalyst loading (S/C=2000).
