  PtBr₂-Catalyzed Consecutive Enyne Metathesis−Aromatization of 1-(1-Methoxy-but-3-enyl)-2-(1-alkynyl)benzenes:  Dual Role of the Pt Catalyst

  摘要：

  1,7-Enynes 1, connected through an aromatic ring and bearing a leaving methoxy group at the 4-position, underwent the PtBr2-catalyzed enyne metathesis followed by aromatization in one pot to afford vinyl naphthalenes 3 in good to acceptable yields. The cyclobutene intermediate 11a and another intermediate 2a were isolated, indicating that PtBr2 acts as a dual role catalyst: (1) as a transition metal catalyst, it induces the eryne metathesis to produce 11a starting from 1a, and (2) as a Lewis acid catalyst, it facilitates elimination of MeOH from 2a to give the aromatized product 3a.

• Direct preparation of substituted olefins from epoxides utilizing lithium tetraalkylcerate

  Alkylated olefins were directly synthesized in good yields by the deoxygenation reaction of epoxides with concomitant introduction of the alkyl group using lithium tetraalkylcerate. Styreneoxide and (1-naphthyl)ethyleneoxide gave terminal olefins, while ethyleneoxide replaced by aliphatic substituent, 1,2-epoxy-4-phenyl butane, afforded internal olefin. The utility of the present method was demonstrated

  通过环氧化物的脱氧反应并同时使用四烷基铈酸锂引入烷基，可以高收率直接合成烷基化烯烃。苯乙烯氧化物和（1-萘基）环氧乙烷产生末端烯烃，而环氧乙烷被脂肪族取代基1,2-环氧-4-苯基丁烷代替，得到内烯烃。本方法的实用性在倍半萜烯，脱氢-α-姜黄素的一步合成中得到了证明。
