Solvent-free and direct C(sp3)–H amination of adamantanes by grinding
摘要:
A facile, direct and environmentally benign conversion of C(sp(3))-H bonds to C(sp(3))-N bonds using substoichiometric amount of aprotic superelectrophiles polyhalomethane-AIX(3) has been achieved by grinding under solvent-free conditions at room temperature in air. It is a general and simple method for the direct amination of adamantanes, and a series of aminoadamantanes of azoles, arylamines or heteroarylamines were obtained in good to excellent yields. The advantages of this amination are atom economy, solvent-free, chemoselectivity, short reaction time and high yields. (C) 2014 Elsevier Ltd. All rights reserved.

and 14 ketones. In our ongoing efforts in preparing tool compounds for investigating and controlling the biosynthesis of phenazines, we recognized the limitations of existing protocols for C–N bond formation of electron-deficient anilines when usingreductiveamination. After extensive optimization, we have established three robust and scalable protocols for the reductiveamination of ketones with electron-deficient
