Gassmann indolsynthese
WebThe Gassman indole synthesis is a series of chemical reactions used to synthesize substituted indoles by addition of an aniline and a ketone bearing a thioether substituent. This is a one-pot chemical reaction, and none of the intermediates are isolated. R1 can be hydrogen or alkyl, while R2 works best with aryl, but can also be alkyl.

WebThe Gassman indole synthesis involves a one-pot process in which a hypohalite, a α-carbonyl sulfide derivative, and a base are added sequentially to aniline or substituted aniline to provide 3-thioalkoxy indole [25]. Mori-Ban reaction involves intramolecular Heck reaction of o-halo-aniline with pendant olefin to prepare indole [26].
