Synthesis of 2-benzoylpyrrole derivatives via C–H functionalization adjacent to nitrogen of pyrrole
摘要:
A direct transition-metal-free synthesis of 2-benzoylpyrrole derivatives from free (N-H) pyrroles and benzaldehyde has been developed. The benzoylation reaction at the 2 or 5-position of pyrrole proceeded well under the alkali metalation system and with 2,6-dimethylaniline as the additive in moderate to good yields. This strategy offers a simple, efficient approach to synthesis of the 2-benzoylpyrrole derivatives. (C) 2015 Elsevier Ltd. All rights reserved.

Palladium catalysed coupling of the 2-iodoBODIPY 3 with a range of anilines and a primary alkylamine succeeds in generating the corresponding 2-aminoBODIPYs. These 2-aminoBODIPY derivatives are non-emissive and quantum chemical calculations and electrochemistry are consistent with charge transfer from the amine substituent. Attenuation of this charge transfer pathway by conversion of the 1,2-phenylenediamine
