4,5,6,7-TETRAHYDROINDOLE

4,5,6,7-Tetrahydro-1H-indole is used in preparation of chiral tetraaryl-substituted Methane. Also, used in preparation of 4-substituted Phenylamidine derivatives used for controlling phytopathogenic microorganisms.

4,5,6,7-Tetrahydroindole was used as reactant in:

• synthesis of ethyl 3-(4,5,6,7-tetrahydroindol-2-yl)-2-propynoate
• preparation of BODIPY dyes
• N-alkylation with chloromethyloxirane
• preparation of hydroindolepropynoate by chemo- and regioselective solvent-free ethynylation
• palladium- and copper-free cross-coupling of halopropynoates
• preparation of carbonylalkenyl indoles via coupling with dicarbonyl compounds
• 1:2 annelation of 4,5,6,7-tetrahydroindole with 1-benzoyl-2-phenylacetylene

4,5,6,7-Tetrahydroindoles, due to their easy aromatization, are good intermediates to synthesize indoles. 4,5,6,7-Tetrahydroindole on condensation with cyanoacetate leads to 1-ethylthio-2-cyano-4,5,6,7-tetrahydrocyclohexa-[c]-3H-pyrrolizin-3-one.
