A mild and convenient synthesis of substituted indolizines from readily available 2-(pyridin-2-yl)acetyl derivatives using (trimethylsilyl)diazomethane is described. The extension of this methodology to the synthesis of indolefrom 2-aminobenzaldehyde is also reported.
Catalyst-free, direct electrooxidative phenol derivatives C(sp3)–H mono- and di-alkylation reaction have been developed. In contrast to previous typical oxidative and electrochemical coupling, this electrosynthetic approach enables selective mono- and di-alkylations through metal- and external oxidant-free mild conditions via easily available electrodes. Advances of this strategy were proven by an
