Domino Alkene-Isomerization–Claisen Rearrangement Strategy to Substituted Allylsilanes
摘要:
A one-pot isomerization Claisen protocol has been developed for the synthesis of highly substituted allylsilanes. Monosilylated divinyl ethers can be isomerized using a cationic iridium(I) catalyst followed by a thermal Claisen rearrangement to provide the allylsilanes in excellent yields and diastereoselectivities.
