The key cyclization of an allylic alkoxyl radical to a carbon-centered ... The 12,13-epoxy-9-hydroperoxide is a known product from the reaction of 13-HPODE and iron or hydrolysis of the methyl ester ...

We have found that a “one-pot” 5-exo cyclization/Claisen rearrangement sequence is a very efficient process that allows the preparation of a number of cycloheptanoid ring systems. The reaction ...
