  Nonpeptide renin inhibitors employing a novel 3-aza (or oxa)-2,4-dialkyl glutaric acid moiety as a P2/P3 amide bond replacement

  摘要：

  A new series of renin inhibitors has been developed. The inhibitors feature a novel replacement for the P2/P3 dipeptide moiety normally associated with renin inhibitors. The dipeptide replacement was a (2S,4S)-3-aza(or oxa)-2,4-di-alkylglutaric acid amide. Extensive structure-activity relationship studies determined that optimum potency was achieved when inhibitors employed a benzyl and butyl group at the C(4) and C(2) carbon position, respectively. In addition, maximum in vitro potency was obtained when the N-terminus was functionalized by incorporating a 4-(1,3-dioxabutyl)piperidine amide. SAR data suggested that the 1,3-dioxabutyl group (methoxymethyl ether) interacted by hydrogen bonding to groups in the S4 domain of renin. This hypothesis was strengthened when a 4-butylpiperidine amide was substituted and inhibitor potency decreased dramatically. Inhibitors employing this novel dipeptide mimic were prepared by coupling the glutaric acid amides with either the transition-state mimic (2S,3R,4S)-2-amino-1-cyclohexyl-3,4-dihydroxy-6-methylheptane (18) or the hydroxyethylene dipeptide isostere. The glutaric acid amides were prepared by two general procedures. The first procedure involved the reductive amination of alpha-amino acid esters with alpha-keto esters. The second procedure involved the displacement reaction of alpha-bromo esters or acids with alpha-amino acid amides.

  有机光催化连续流中 O2 将三烷基胺 N-CH3 氧化为 N-甲酰胺

  摘要：

  我们报道了连续流中三烷基胺的有机光催化、N-CH 3选择性氧化。基于9,10-二氰基蒽（ DCA ）核心，设计了一种带有增溶基团的流动处理新型催化剂（ DCAS ）。这使得 O 2可以作为一种可持续的氧化剂，用于复杂天然产物和带有先前方法无法耐受的官能团的活性药物成分的后期光催化 N-CH 3氧化。有机光催化气液流动过程比间歇模式提供更清洁的反应，停留时间短，为 13.5 分钟，生产率高达每天 0.65 克。光谱和计算机理研究表明，与难溶性DCA相比，催化剂衍生化不仅提高了新催化剂的溶解度，而且深刻地将光催化机制从单线态电子转移 (SET) 胺还原猝灭转向能量转移 (E n T)氧2 。
