| Reactant | Ethyl 2-(diethoxyphosphoryl)butanoate | HCID 229053 | — |
| Reactant | Retinal | HCID 638015 | — |
| Product | Ethyl 5,9-dimethyl-2-ethyl-11-(2,6,6-trimethyl-1cyclohexen-1-yl)-2,4,6,8,10-undecapentaenoate | HCID 54016105 | — |
Reaction Steps
In analogy to the procedure given in Example 1: Triethyl 2-phosphonobutyrate was reacted with retinal to give ethyl 5,9-dimethyl-2-ethyl-11-(2,6,6-trimethyl-1-cyclohexen-1-yl)-2,4,6,8,10-undecapentaenoate, which was converted by the procedure of Example 2 to 5,9-dimethyl-2-ethyl-11(2,6,6-trimethyl -1-cyclohexen-1-yl)-2,4,6,8,10-undecapentaenoic acid, m.p.=164°-165° C.
