Selective C-2 alkylation of tryptophan by a Pd(II)/norbornene-promoted C-H activation reaction.
J. Org. Chem. 78, 12263-12267 (2013)
A palladium(II)-catalyzed norbornene-mediated regioselective alkylation at the C-2 indole position of N-tert-butyloxycarbonyl (Boc)-protected (S)-tryptophan ethyl ester is reported. The protocol employs mild reaction conditions and is tolerant of a range of functional groups. The reaction proceeds without racemization at the stereogenic center of the amino acid.
