Participants

Reaction Steps

A solution of ethyl 3-(2-allyloxyphenyl)-4,4-diethoxy-2-ethoxycarbonylbutanoate (described in Example 1(i)), in ether is treated with sodium ethoxide and subsequently with methyl iodide to give ethyl 3-(2-allyloxyphenyl)-4,4-diethoxy-2-ethoxycarbonyl-2-methylbutanoate, which is subsequently reacted in a manner similar to that described in Example 1(i) to give 4-(2-allyloxyphenyl)-5-ethoxy-3-methyl-2-oxotetrahydrofuran.
