Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | 4-Fluorobenzaldehyde | HCID 68023 | — |
| Reactant | L-Tryptophan, methyl ester | HCID 77980 | — |
| Product | methyl 1-(4-fluorophenyl)-2,3,4,9-tetrahydro-1H-beta-carboline-3-carboxylate | HCID 4691803 | — |
Reaction Steps
The same method as employed in the preparation of intermediate 1 and 2 but starting from racemic tryptophan methyl ester and 4-fluorobenzaldehyde gave the cis isomer as white crystals m.p.: 92° C. and the trans isomer as pale yellow crystals m.p.: 183° C.
