group in the asymmetric aminohydroxylation reaction of but-3-en-1-ol derivatives. Either regioisomeric product can he obtained with useful levels of eoantioselectivity, allowing for the short enantioselective synthesis of GABOB and homoserine derivatives.
A general study of the iron‐catalyzedreaction of urea with nucleophiles is here presented. The carbamoylation of alcohols allows for the synthesis of N‐unsubstituted (primary) carbamates, including present drugs (Felbamate and Meprobamate), without the necessity to apply phosgene and related derivatives. Using amines as nucleophiles gave rise to the respective mono‐ and disubstituted ureas via selective

carbamates with unactivated secondary alkyl bromides at room temperature. Our mechanistic observations are consistent with the newcoppercomplex serving its intended role as a photoredox catalyst, working in conjunction with a second coppercomplex that mediates C-N bond formation in an out-of-cage process.
尽管氮亲核试剂和烷基亲电试剂之间的 SN2 反应历史悠久,但许多此类取代反应仍然遥不可及。近年来,开发过渡金属催化剂以解决这一缺陷的努力已经开始出现。在本报告中,我们解决了将氨基甲酸酯亲核试剂与未活化的仲烷基亲电试剂偶联以生成取代氨基甲酸酯的挑战,这一过程在没有催化剂的情况下无法有效实现;氨基甲酸酯产品本身可用作有机合成中的有用中间体以及生物活性化合物。通过设计和合成一种新的铜基光氧化还原催化剂,带有三齿咔唑/双膦配体,可以在蓝光 LED 灯照射下激活,我们可以在室温下实现一系列伯氨基甲酸酯与未活化的仲烷基溴的偶联。我们的机械观察结果与新的铜配合物作为光氧化还原催化剂的预期作用一致,与第二种铜配合物协同工作,后者在笼外过程中介导 CN 键的形成。
