  Structure−Activity Relationship of an Ozonide Carboxylic Acid (OZ78) againstFasciola hepatica

  摘要：

  In this paper, we describe the SAR of ozonide carboxylic acid OZ78 (1) as the first part of our search for a trematocidal synthetic peroxide drug development candidate. We found that relatively small structural changes to 1 resulted most commonly in loss of activity against Fasciola hepatica in vivo. A spiro-adamantane substructure and acidic functional group (or ester prodrug) were required for activity. Of 26 new compounds administered at single 100 mg/kg oral doses to F. hepatica infected rats, 8 had statistically significant worm burden reductions, 7 were partially curative, and 1 (acylsulfonamide 6) was completely curative and comparable to 1 in flukicidal efficacy. This study also showed that the activity of 1 is peroxide-bond-dependent, suggesting that its flukicidal efficacy depends upon hemoglobin digestion in F. hepatica.

  In this paper we describe new multi-catalysis cascade (MCC) reactions for the one-pot synthesis of highly functionalized non-symmetrical malonates. These metal-free reactions are either five-step (olefination/hydrogenation/alkylation/ketenization/esterification) or six-step (olefination/hydrogenation/alkylation/ketenization/esterification/alkylation), and employ aldehydes/ketones, Meldrum's acid, 1,4-dihydropyridine/o-phenylenediamine, diazomethane, alcohols and active ethylene/acetylenes, and involve iminium-, self-, self-, self- and base-catalysis, respectively. Many of the products have direct application in agricultural and pharmaceutical chemistry.

  在本文中，我们描述了一种新的多重催化级联反应（MCC），用于一锅合成高度功能化的非对称马来酸酯。这些无金属催化反应分为五步（烯化/加氢/烷基化/酮化/酯化）或六步（烯化/加氢/烷基化/酮化/酯化/烷基化），涉及醛/酮、梅尔德伦酸、1,4-二氢吡啶/邻苯二胺、重氮甲烷、醇以及活性乙烯/炔烃，分别涉及亚胺、各自、自我、自我和碱催化。许多产品在农业和制药化学中具有直接应用。
