Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | 3-(3,4-Dimethoxyphenyl)-4,4-diethoxy-2-ethoxycarbonylbutyric acid ethyl ester | HCID 15521372 | — |
| Reactant | 4,4-Diethoxy-2-ethoxycarbonyl-3-(4-methoxy-3-phenethyloxyphenyl)butyric acid ethyl ester | HCID 54339607 | — |
| Product | 4,4-Diethoxy-3-(4-methoxy-3-phenethyloxyphenyl)butyric acid | HCID 21994470 | 51.4% |
Reaction Steps
Using the same procedure as in Example 1 (3), 4,4-diethoxy-2-ethoxycarbonyl-3-(4-methoxy-3-phenethyloxyphenyl)butyric acid ethyl ester, instead of 3-(3,4-dimethoxyphenyl)-4,4-diethoxy-2-ethoxycarbonyl butyric acid ethyl ester, was used to obtain a light yellow solid of above-described compound (51.4%) via 4,4-diethoxy-3-(4-methoxy-3-phenethyloxyphenyl)butyric acid (yield 51.4%).
