has been achieved in 12 steps from (2E,5E)-1,7-dibenzyloxy-2,5-heptadiene-4-ol employing Red-Al®-promoted reductive cleavage of the benzyl 4-hydroxy-2-butenyl ether structure and ruthenium catalyzed olefin metathesis as key steps.
(+)的有效对映选择性合成- aspicilin已经在从(2 12个步骤已经实现ë,5 ë)-1,7-二苄基-2,5-庚二烯-4-醇采用红铝®促进的还原裂解苄基4-羟基-2-丁烯基醚结构和钌催化的烯烃复分解是关键步骤。
