ylethyl)furan‐2‐yl]methyl}phenol (2), were synthesized starting from 2‐furaldehyde. A Wittig reaction of 2‐furaldehyde with benzyltriphenylphosphonium bromide followed by reduction of the alkene CC bond with Mg gave 2‐(2‐phenylethyl)furan (5). Lithiation of 5 with BuLi at −78° followed by alkylation with benzyl bromide gave natural product 1. In another approach, FriedelCrafts acylation of compound
合成了两种天然的二芳基庚烷,2-苄基-5-(2-苯乙基)呋喃(1)和2-甲氧基-4-[[5-(2-苯乙基)呋喃-2-基]甲基}苯酚(2)从2-呋喃甲醛开始。2-呋喃甲醛与溴化苄基三苯基Wi的Wittig反应,然后通过Mg还原烯烃CC键得到2-(2-苯基乙基)呋喃(5)。在-78°下用BuLi进行5的锂化,然后用苄基溴进行烷基化,得到天然产物1。在另一方法中,在Friedel 工艺品化合物的酰化5与苯甲酰氯,接着,得到CO组的脱氧1。天然产物2也可以通过将5与4-乙酰氧基-3-甲氧基苯甲酰氯酰化(16),然后进行脱氧和脱乙酰化来合成。
