An enantioselective copper‐catalyzed asymmetric conjugate addition of Me2Zn to (Z)‐nitroalkenes led to the formation of all‐carbon quaternary stereogenic centers with high stereoselectivity. The key features of the new method are the unprecedented use of [(MeCN)4Cu]PF6 in conjunction with the Hoveyda ligand L1 and the use of (Z)‐nitroalkene substrates so that undesired nitroalkene isomerization is
Me 2 Zn对(Z)-硝基烯烃的对映选择性铜催化不对称共轭加成导致形成具有高立体选择性的全碳四元立体中心。新方法的关键特征是[[MeCN)4 Cu] PF 6与Hoveyda配体L1的空前使用以及(Z)-硝基烯烃底物的使用,从而使不希望的硝基烯烃异构化最小化,对映选择性大大提高。 。我们还描述了一种新颖,实用且高度(Z)选择性的硝基烯烃合成方法。

N-heterocyclic carbenes (NHCs) have emerged as catalysts for the construction of C−C bonds in the synthesis of substituted ketones under single-electron processes. Despite these recent reports, there still remains a need to increase the utility and practicality of these reactions by exploring new radical coupling partners. Herein, we report the synthesis of γ-aryloxyketones via combined NHC/photoredox

Triazolothiadiazoles are potent antitubercular agents with modest inhibitory forMtSD and without appreciable cytotoxicity.
三唑噻二唑是一种具有较强抗结核活性的药物,对MtSD有适度的抑制作用,并且没有明显的细胞毒性。
Ketoreductase catalyzed stereoselective bioreduction of α-nitro ketones
the best of our knowledge, KRED-mediated reduction of class II α-nitro ketones (1-aryloxy-3-nitro-2-propanone (4)) is unprecedented. Select β-nitro alcohols, including the synthetic intermediates of bioactive molecules (R)-tembamide, (S)-tembamide, (S)-moprolol, (S)-toliprolol and (S)-propanolol, were stereoselectively synthesized in preparative scale with 42% to 90% isolated yields, showcasing the
