  Discovery and SAR studies of methionine–proline anilides as dengue virus NS2B-NS3 protease inhibitors

  摘要：

  A series of methionine-proline dipeptide derivatives and their analogues were designed, synthesized and assayed against the serotype 2 dengue virus NS2B-NS3 protease, and methionine-proline anilides 1 and 2 were found to be the most active DENV 2 NS2B-NS3 competitive inhibitors with K-i values of 4.9 and 10.5 mu M. The structure and activity relationship and the molecular docking revealed that L-proline, L-methionine and p-nitroaniline in 1 and 2 are the important characters in blocking the active site of NS2B-NS3 protease. Our current results suggest that the title dipeptidic scaffold represents a promising structural core to discover a new class of active NS2B-NS3 competitive inhibitors. (C) 2013 Elsevier Ltd.

  使用 N-芳基脯氨酰胺作为具有增强酸度的有机催化剂在常见有机溶剂中的高度非对映选择性和对映选择性羟醛反应

  摘要：

  已经合成了一系列具有增加的 NH 酸度和空间拥挤的 N-芳基脯氨酰胺 1-8，并探索了其对对映选择性醛醇反应的催化活性。在含有 10 mol% TFA 的 DMF 中，发现所有芳基酰胺都能催化环己酮和各种亲电子醛之间的反应，导致醛醇的产率超过 90%，对映选择性大于 95%。与所有其他 N-芳基酰胺 1-7 相比，发现全氟苯基催化剂 8 在广泛的底物范围内表现最佳。结果表明，8 确实可以在高度非极性以及极性溶剂（包括盐水）中使用，以提供具有优异非对映选择性和对映选择性的高收率醛醇。对于不含额外立体中心和氢键位点的脯氨酰胺，对 8 观察到的结果是迄今为止报道的最好的结果之一。7 和 8 的分子结构，通过 X 射线晶体学确定并被认为反映了最稳定的构象，揭示了 N-芳环构象的显着差异；在 7 的情况下，芳环表现出与酰胺官能团共面的趋势，而在 8 的情况下，全氟苯环相对于官能团的酰胺平面几乎垂直扭曲。

  steric crowding has been synthesized and its catalytic activity explored for enantioselective aldol reactions. In DMF containing 10 mol-% of TFA, all arylamides are found to catalyze the reaction between cyclohexanone and a variety of electrophilic aldehydes leading to aldols in excess of 90 % yield and >95 % enantioselectivity. The perfluorophenyl catalyst 8 is found to perform best with a broad substrate

  Simple pyrrolidine-based chiral amines were synthesized and used for the Michael addition of different ketones to a variety of nitro-olefins in brine. The effect of different surfactants and acids on the yields and stereochemical outcome of the Michael adducts was studied in detail. Chiral amine 1g was found to catalyze the formation of Michael adducts with high enantioselectivity (up to >99%), diastereoselectivity [up to 98:2 (syn:anti)] and yield (up to 94%).

• Simple, inexpensive, and facile l-prolinamide used as a recyclable organocatalyst for highly efficient large-scale asymmetric direct aldol reactions

  In order to discover a simple, inexpensive, and efficient route to obtain highly enantiomerically enriched anti-aldol products for applications in industry, a series of prolinamides 1-5 with different carbocyclic rings have been synthesized from achiral cycloalkylamine, and prolinamides 6-9 have been synthesized from aniline with different substituents. The organocatalysts obtained catalyzed the asymmetric aldol reaction and showed that no matter carbocyclic rings or aromatic rings were found to play a significant role in the formation of the aldol products. Moreover, the prolinamide 6 exhibited efficient catalytic activity in the asymmetric aldol reaction only with 5 mol % catalyst loading and 4 equiv of ketone, and afforded aldol products in high diastereoselectivity (up to anti/syn 99:1) and enantioselectivity (99%) and significantly enhanced the reaction yield (99%). These results were much better than L-proline-3-nitroanilide which had the strongest electron-withdrawing group on the aromatic ring. Furthermore, catalyst 6 can be easily recovered and reused, without a significant decrease of enantioselectivity after five cycles. This inexpensive, simple, and recyclable catalyst can be efficiently used in large-scale reactions with the enantioselectivities being maintained at the same level, which offers a great possibility for application in industry.
