α-手性胺是大规模制备生物活性化合物的关键中间体;在此,我们提出了一种新型的钯基纳米催化剂,能够选择性催化羰基化合物的还原胺化,从而能够原位催化使用 ω-转氨酶从单酶级联中的浪费副产物中再生氨基供体,而不需要昂贵的辅酶 NAD(P)H。该级联网络将 ω-转氨酶辅助的转氨反应与由异质钯基纳米催化剂促进的选择性还原胺化反应结合起来。氮源自羟胺离子,将生成的副产物转化回氨基供体,产生收率高达 99% 的手性胺,并具有出色的对映选择性。这种化学酶单酶转氨作用-还原胺化级联网络具有很高的原子效率,并产生 H 2 O 作为其唯一的副产物,证明了其在合成化学及其他领域的潜在影响。

linked to depression, schizophrenia (SCZ), and substance-use disorder. High-throughput screening and a medicinal chemistry structure–activity relationship strategy identified a novel series of potent and selective benzotriazinone-based GPR139 agonists. Herein, we describe the chemistry optimization that led to the discovery and validation of multiple potent and selective in vivo GPR139 agonist tool

A one‐pot deracemization strategy for α‐chiral amines is reported involving an enantioselective deamination to the corresponding ketone followed by a stereoselective amination by enantiocomplementary biocatalysts. Notably, this cascade employing a ω‐transaminase and amine dehydrogenase enabled the access to both (R)‐and (S)‐amine products, just by controlling the directions of the reactions catalyzed
