  可重复使用的铜基生物质碳气凝胶催化剂的制备及其在氢硅烷为氢源高选择性还原马来酰亚胺生成琥珀酰亚胺中的应用

  摘要：

  选择性还原是有机合成中最重要和最常用的转化之一。在这项工作中，我们开发了一种新型铜基生物质碳气凝胶催化剂（Cu(OTf) 2 @CAC），作为一种高效、选择性的催化剂，首次以氢硅烷作为氢源进行马来酰亚胺还原。设计了一种集甲壳素溶解、纳米纤维再生、气凝胶构建和可定制碳化于一体的策略，用于将三氟甲磺酸铜(Cu(OTf) 2 )在CAC上还原为Cu(0)和Cu( I )。Cu(OTf) 2 @CAC 在温和条件下选择性马来酰亚胺还原为琥珀酰亚胺时表现出优异的催化活性、化学选择性和可回收性。此外，Cu(OTf) 2 @CAC可以重复使用六次而不会明显失去活性。该工作为基于废弃生物质资源的再加工和可定制处理实现高效催化转化提供了具有代表性和参考性的方法。

  N-取代的马来酰亚胺衍生物作为选择性甘油单酯脂肪酶抑制剂的合成及体外评价

  摘要：

  内源性大麻素2-花生四烯酸甘油酯（2-AG）在许多生理过程中起着重要作用，其作用通过甘油单酯脂肪酶（MGL）催化的酶促水解迅速终止。调节其内源水平可以提供治疗机会；然而，到目前为止，几乎没有描述选择性的MGL抑制剂。在这里，我们描述了N-取代的马来酰亚胺的合成及其对重组人脂肪酸酰胺水解酶（FAAH）和纯化人MGL的药理评价。先前已经描述了一些N-芳基马来酰亚胺（萨里奥（SM）；萨洛（OM）；Nevalainen，T .；Poso，A。莱蒂宁（JT）；贾文恩（T.
