Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Acetaldehyde | HCID 177 | — |
| Reactant | L-(+)-Cysteine | HCID 5862 | — |
| Product | 2-Methyl-4-thiazolidinecarboxylic acid | HCID 160736 | — |
Reaction Steps
Acetaldehyde (0.27 g) and L-cysteine (0.75 g) were reacted in aqueous solution 10 ml at room temperature for 1.5 hours, followed by solvent evaporation evaporated in vacuo. The resulting product was recrystallized from methanol to yield the title compound. Melting Point: 161°-163° centigrade Optical Rotation [α]26D: -148°.
