The Catalytic Synthesis of -Aryl Indoles Featuring an Alternative Disconnection. Hydroaminoalkylation for a Telescoped Reaction Sequence.

A tricatalytic telescoped synthesis toward C3-methyl--aryl indoline and indole products is reported. An generated tantalum(V) ureate catalyst is used for the hydroaminoalkylation of -chlorostyrene with -methylaniline to first make a C─C bond. Subsequent nickel-catalyzed C-N coupling forms -aryl indolines, and if desired, subsequent oxidation to -aryl indoles can be achieved using catalytic [Cu(MeCN)]BF and -butylperoxy-2-ethylhexyl carbonate as the terminal oxidant.

[Endoscopic surgery for benign diseases and injuries of the esophagus (with commentary)].

Aim: To analyze the results of surgical treatment of patients with benign diseases and injuries of the esophagus.

Material And Methods: We summarized the experience of different endoscopic interventions in 159 patients with various benign diseases and perforation of the esophagus. Patients with achalasia (72 cases) underwent videolaparoscopic Geller's esophagomyotomy with anterior hemiesophagofundoplication by Dor.
