ethyl 4-methylpent-3-enoate

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: On the other hand, the isomerization of ethyl 4-methyl-4-pentenoate to ethyl tratis-4-methyl-2-pentenoate is not favored thermodynamically. In fact the equilibrium distribution of isomers at 25° C. is as follows: ethyl 4-methyl-3-pentenoate (90%) and ethyl 4-methyl-2-pentenoate (10%). Despite this adverse equilibrium, ethyl 4- methyl-trans-2-pentenoate is obtained in 90% yield using the process of the present invention. The isomerization of ethyl 4-methyl-4-pentenoate also shows that this method accommodates the isomerization of olefin-esters that contain a tertiary carbon. at 25° C.
