A meaningful copper-catalyzed chemo-selective oxidative alkylamination of maleimides with secondary alkyl amines and simple alkanes has been developed. This transformation exhibits excellent compatibility with an array of polyfunctionalized organic amines and inactivated alkanes, modular synthesis of 3-carbo-4-amino maleimides under simple, and efficient catalytic systems. Detailed mechanistic studies
This disclosure relates to reagents and methods useful in the synthesis of aryl iodines, for example, in the preparation of iodine labeled radiotracers. The reagents and methods provided herein may be used to access a broad range of compounds, including aromatic compounds, heteroaromatic compounds, amino acids, nucleotides, and synthetic compounds.
A highly enantioselective approach has been developed for synthesising chiral succinimide derivatives via asymmetric Michael addition of diketones to maleimide using dihydroquinine as a catalyst in brine. The Michael adducts were obtained in yields up to 98% and with enantiomeric excesses up to 98% ee. (C) 2016 Elsevier Ltd. All rights reserved.
