The Uses of 5-Benzyloxyindole
5-Benzyloxyindole is used as reagent/reactant in regioselective preparation of CF3-β-tryptamine derivatives via base-free thermal ring-opening reaction of N-nosyl-2-CF3-aziridine with indoles.
The Uses of 5-Benzyloxyindole
Reactant in regio- and stereoselective morpholine-catalyzed direct C-3 alkenylation with α,β-unsaturated aldehydes Reactant in selective debenzylation of protective groups using SiliaCat-palladium under mild reaction conditions Reactant in metal-free Friedel-Crafts alkylation reactions Reactant in preparation of protein kinase (PKC) inhibitors Reactant in preparation of indole/quinoline carbothioic acid amide derivatives.
