The direct conversion of allyl ethers to cyclic enol ethers using an olefin metathesis/double bond migration sequence is described. Ruthenium carbene complexes were activated to catalyze the double bond migration step by addition of hydride sources, such as NaH or NaBH4. (© Wiley-VCH Verlag GmbH & Co.

描述了使用烯烃复分解/双键迁移序列将
烯丙基醚直接转化为环状烯醇醚。通过添加
氢化物源,例如 NaH 或 NaBH4,
钌卡宾配合物被激活以催化双键迁移步骤。(© Wiley-
