Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | D-Cysteine | HCID 92851 | — |
| Reactant | 2-Methylthiazolidine-2,4-dicarboxylic acid 2-ethyl ester | HCID 86680929 | — |
| Product | N-acetyl-2-methylthiazolidine-2,4-dicarboxylic acid 2-ethyl ester | HCID 54760676 | — |
Reaction Steps
By a method similar to that in Synthetic Example 7 except for the use of 2-methylthiazolidine-2,4-dicarboxylic acid 2-ethyl ester synthesized from D-cysteine by a method similar to that in Reference Example 2, N-acetyl-2-methylthiazolidine-2,4-dicarboxylic acid 2-ethyl ester was obtained (with the ratio of cis form:trans form of about 43:57 as confirmed by NMR).
