Methods for preparing 5-Acetoxy-(E3)-3-pentenyl methoxymethyl ether and an (E3)-3-alkenyl acetate |
摘要 |
<p>Provided are 5-acetoxy-(E3)-3-pentenyl methoxymethyl ether which can be prepared in conventional reaction equipment and a method for preparing an (E3)-3-alkenyl acetate by using it. More specifically, 5-hydroxy-(E3)-3-pentenyl methoxymethyl ether obtained by reacting 4-formyl-(E3)-3-butenyl methoxymethyl ether with a reductant is reacted with an acetylating agent to prepare 5-acetoxy-(E3)-3-pentenyl methoxymethyl ether. (E3)-3-alkenyl methoxymethyl ether obtained by a coupling reaction between the 5-acetoxy-(E3)-3-pentenyl methoxymethyl ether and a Grignard reagent is treated with an acid, and then reacted with an acetylating agent to prepare the (E3)-3-alkenyl acetate.</p> |
