通过简单,有效且对环境有益的方法将各种硫化物选择性氧化为亚砜是首要目标。在本文中,我们探索了一种高效的方案,用于在70%t存在下将La 2 O 3催化的烷基芳基硫醚氧化为亚砜的高选择性。-BuOOH溶液(水)。我们主要获得单加氧产物。在这些条件下未观察到硫化物过度氧化为砜。在不使用配体和其他添加剂的情况下,在合理的时间内以良好至极好的收率获得了所得产物。用烯丙基硫未观察到双键的环氧化以及烯丙基氧化。可以通过改变反应条件来定量获得砜。通过XRD,AFM和SEM技术对表面形貌和催化剂的可重复使用性进行了验证。使用BET等温线测量La 2 O 3的表面积。

intracellular cysteine amidase, N‐acylethanolamine acid amidase (NAAA). Even though NAAA may offer a new target for anti‐inflammatory therapy, the lipid‐like structures and reactive warheads of current NAAAinhibitors limit the use of these agents as oral drugs. A series of novel benzothiazole–piperazine derivatives that inhibitNAAA in a potent and selective manner by a non‐covalent mechanism are
