The Formation of 7-Oxabicyclo[4.2.0]octanes and 6-Oxabicyclo[3.2.1]octanes via Cationic Iodocyclization
摘要:
Several 2-cyclohexenemethanol derivatives were subjected to cationic iodocyclization. Two product types were formed: the fused 7-oxabicyclo[4.2.0]octane, and the bridged 6-oxabicyclo[3.2.1]octane. The degree of substitution in the alkenol determined the ratio of the products, with aromatic substituents leading to the formation of the fused system as the major product.
