Reported herein is an effective strategy for oxidative cross-coupling of indoles with various aldehydes. The strategy is based on a two-step transformation via a well-known Mannich-type reaction and a C-N bond cleavage for carbonyl introduction. The key step - the C-N bond cleavage of the Mannich product - was enabled by electrochemistry. This strategy (with over 40 examples) ensures excellent functional-group tolerance as well as late-stage functionalization of pharmaceutical molecules.
Synthesis of highly substituted indole alkaloid species via [4+1] cyclization of nucleophilic carbenes and indole isocyanates

Thermally induced [4+1] cyclization between indole isocyanates and dimethoxycarbene or bis(propylthio)carbene has been achieved with good chemical efficiency. The methodology provides rapid access to fused pyrroloindole substructures commonly found in a variety of indole alkaloid natural products.
