1-Methylindole-2-carboxaldehyde may be used in the synthesis of indole-based melatonin analog hydrazone derivatives and (E)-5-((benzyloxy)methyl)-5-(((tert-butyldiphenylsilyl)oxy)methyl)-3-((1-methyl-1H-indol-2-yl)methylene)dihydrofuran-2(3H)-one.

Reactant for preparation of:

• Deazapurine isosteres from acylindoles via pyridine ring annulation
• 2,4-dichlorocinnamohydroxamic acid analogs for enhancing pharmacokinetics of botulinum neurotoxin serotype A protease inhibitors
• Tetrahydrocarbazoles via organocatalytic cascade Friedel-Crafts alkylation/Michael addition/aromatization reaction
• Azides, imines and amines via flow processes of amines and trimethylsilyl azide and aza-Wittig reaction
• 3-indolylpyridinedicarbonitriles as anti-inflammatory agents
• Bis(indolyl)methanes as antimicrobial and antioxidant agents
