YieldReaction ConditionsOperation in experiment
With LiOH; trifluoroacetic acid; In tetrahydrofuran; methanol; dichloromethane; toluene; Synthesis of Cbz-protected methoxytryptophane 10 Trifluoroacetic acid (0.5 mL) was added dropwise to a solution of methoxytryptophane 9 (95 mg, 0.20 mmol) in dichloromethane (4 mL) at 0 C. The reaction mixture was stirred for 3.5 hours at room temperature. The solution was concentrated by co-evaporation with toluene (3 x 5 mL) and the resulting deprotected tryptophane was used directly in the next step. A 0.5 N aqueous solution of LiOH (0.8 mL, 0.4 mmol) was added to a solution of the deprotected tryptophane in tetrahydrofurane/methanol/water (7:1.3:4 mL) at 0 C. The reaction mixture was warmed to room temperature and stirred for 2 hours. The solution was partitioned between 0.1 N aqueous HCl (15 mL) and dichloromethane (15 mL). The aqueous layer was extracted with dichloromethane (2 x 15 mL) and the organic layers were combined, dried (Na2SO4) and concentrated. The residue was purified by column chromatography (dichloromethane with a gradient of 1 to 5% methanol) to give 51 mg of Cbz-protected methoxytryptophane 10 as a white solid (0.14 mmol, 70%, 2 steps). Rf = 0.27 (Ethyl acetate /n-hexane 3:1, with 1% acetic acid);

The aqueous layer was extracted with dichloromethane (2 x 15 mL) and the organic layers were combined, dried (Na2S04) and concentrated. The residue was purified by column chromatography (dichloromethane with a gradient of 1 to 5% methanol) to give 51 mg of Cbz-protected methoxytryptophane 2 as a white solid (0.14 mmol, 70%, 2 steps).Rf= 0.27 (Ethyl acetate /«-hexane 3:1 , with 1 % acetic acid);["Eg = .44.3 (c = 0.3, MeOH)1H-NMR (400 MHz, [D6]DMSO, 60 C): delta = 10.75 (br, s, 1H), 7.41 (d, J = 8 Hz, 1H), 7.24-7.34 (m, 5H), 6.9-7.2 (m, 3H), 6.44 (d, J = 7 Hz, 1H), 4.95 (m, 2H), 4.30 (m, 1H), 3.83 (s, 3H), 3.35 (dd, J = 14, 4 Hz, 1H), 2.95 (dd, J = 14, 10 Hz, 1H).

YieldReaction ConditionsOperation in experiment
To a suspension of 5-Methoxy-L-tryptophan (1 g; 4.27 mmol) in MeOH (5 mL) at 0 C thionyl chloride (0.37 mL; 5.12 mmol) was added dropwise. The mixture was refluxed for 4 hours. HPLC-MS showed no starting material . P-anisaldehyde was added over the heating solution (756 mg; 1.1 equiv.) and the mixture was stirred overnight. HPLC-MS after 14 hours showed two diastereoisomers (79%).The mixture was cooled to room temperature and was concentrated to dryness. The resulting crude was dissolved in water (50 mL). DCM was added (20 mL) and saturated NaHC03 was added until pH=7. The layers were separated and the aqueous phase was extracted with DCM. The combined organic layers were washed with H20 and brine, dried over Na2S04, filtered and concentrated to dryness. The residue (1.85g) was purified by flash chromatography (Si02, Hexane/AcOEt 3: 1) obtaining 226 mg of the mixture of diastereoisomers of compound 14c (J HG-1117-49CF1). Yield: 15%. HPLC-Ms: 95%. Another unidentified impurity was obtained (800mg), likely due to degradation.
