Molbank, Vol. 2018, Article M985: Gold-Catalyzed Synthesis of 2-Sulfenylspiroindolenines via Spirocyclizations

Authors: Valentin Magné Pascal Retailleau Angela Marinetti Arnaud Voituriez Xavier Guinchard

2-Phenylsulfenyl-N-propargyl tryptamines have been prepared by electrophilic sulfuration of the corresponding tryptamines. These compounds undergo gold-catalyzed spirocyclizations to the corresponding 2-phenylthiospiroindolenines in good yields. The compounds were analyzed by NMR experiments, infrared, mass spectra and X-ray diffraction. This method provides a new efficient entry to the synthesis of 2-sulfenyl spiroindolic compounds.
