Regioselective electrophilic fluorination of indoles: syntheses of 4-fluoroserotonin and 4-fluoromelatonin
摘要:
Reaction of N-triisopropylsilyl-5-methoxygramine with t-butyllithium produces the 4-lithio derivative. Electrophilic fluorination with N-fluorobenzenesulfonimide (NFSi) followed by deprotection and side-chain elaboration provide convenient syntheses of 4-fluoroserotonin and 4-fluoromelatonin, new analogs of these important neurochemicals.
