PdII-catalysed isomerisations of 3-acetoxy-1,4-dienes to 1-acetoxy-2,4-dienes: stereochemical and preparative aspects
Abstract
The rapid PdII-catalysed rearrangement of 3-acetoxy-1,4-dienes to 1-acetoxy-2,4-dienes [e.g.(2E,5Z)-4-acetoxydeca-2,5-diene →(3E,5Z)-2-acetoxydeca-3,5-diene (ca. 80%)] occurs in stereoselective and regio-selective manner.
