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-[3-(2-ethylbutoxy)-4-methoxyphenyl]butyric acid ethyl ester | HCID 21994476 | — |
| Product | 4,4-Diethoxy-3-[3-(2-ethylbutoxy)-4-methoxyphenyl] butyric acid | HCID 21994485 | 36.9% |
Reaction Steps
Using the same procedure as in Example 1(3), 4,4-diethoxy-2-ethoxycarbonyl-3-[3-(2-ethylbutoxy)-4-methoxyphenyl]butyric acid ethyl ester, instead of 3-(3,4-dimethoxyphenyl)-4,4-diethoxy-2-ethoxycarbonylbutyric acid ethyl ester, was used to obtain a yellow solid of the above-described compound via 4,4-diethoxy-3-[3-(2-ethylbutoxy)-4-methoxyphenyl] butyric acid (yield 36.9%).
