the benzofuro[3,2‐b]indoline framework could be obtained by PIDA‐mediated direct oxidative coupling of 2,3‐disubstituted‐indoles with phenols. Application of this chemistry allows for an eight‐step total synthesis of phalarine from commercially available tryptamine.

The electrophilic potential of diazirines has been utilized to obtain N-substituted diaziridines that are directly hydrolyzed to produce monosubstituted hydrazines. The hydrazines can undergo the Fisher process with enolizable carbonyls to yield multiple indole derivatives in moderate to high yields. The N-metalated diaziridine intermediates can undergo isomerization prior to electrophilic substitution
A green and regioselective electrooxidative coupling reaction between indoles and phenols for the synthesis of benzofuro[3,2-b]indolines was developed. A variety of benzofuro[3,2-b]indolines were prepared in moderate to excellent yields. A plausible mechanism was proposed.
