A new, general entry to 4-substituted indoles. Synthesis of (S)-(−)-pindolol and (±)-chuangxinmycin
Hiroyuki Ishibashi,Takashi Tabata,Kyoko Hanaoka,Hiroko Iriyama,Susumu Akamatsu,Masazumi Ikeda +5 more
TL;DR: In this article, a new method for synthesis of 4-substituted indoles has been developed by using the 7-arylthio-6-7-dihydroindol-4(5H) one5 as a common intermediate.

Synthesis of ortho-Substituted Arylacetic Esters and Related Compounds by Means of Sommelet-Hauser Rearrangement of Sulfur Ylides
TL;DR: In this article, a series of dimethylsulfonium α-substituted benzylides, e.g., 8, have been examined in situ by treatment of the sulfonium salts 7a, b with 1, 8-diazabicyclo[5.4]undec-7-ene (DBU) in ethanol at room temperature, afforded the o-(methylthiomethyl)phenylacetic esters 10a,b as a result of the Sommelet-Hauser rearrangement of the taut
