WebRelated Reactions Fischer Indole Synthesis Multicomponent Reactions Synthesis of thiophenes. Gewald Reaction. The Gewald Reaction is a synthesis of 2-aminothiophenes via a multi-component condensation between sulfur, an α-methylene carbonyl compound and an α-cyanoester. WebThese reactors thus allow reactions that were previously considered impractical for the teaching laboratory, such as the Fischer indole synthesis, to now be very feasible. We designed a clean and efficient Fischer indole synthesis to introduce advanced undergraduate students to this important method in heterocycle synthesis, which has …
