Oxidative C(Sp3)–H activation and C–N cleavage of N-methyl amines under transition-metal-free condition for synthesis of methylene-bridged bis-1,3-diketones
摘要:
A transition-metal-free oxidative methylenation reaction was developed. Methylene-bridged bis-1,3-dicarbonyl compounds were synthesized by oxidative C(Sp(3))-H activation and C-N cleavage of N-methyl amines. This novel reaction avoids the use of transition metal catalyst. Furthermore, the reaction are very mild and operational convenient. (C) 2014 Elsevier Ltd. All rights reserved.

simple and convenientprocedure for the preparation of valuable bis-1,3-dicarbonyl-substituted methane compounds and their derivatives has been developed using inert dichloromethane as one-carbon source in good to excellent yields. The advantages of this protocol are mild reaction conditions, easily scalable and good functional group compatibility. Moreover, the use of cyclic secondaryamine as the promoter
