Abstract
In this paper we report the preparation of the benzyltetrahydropyran fragment of the vacuolar ATPase inhibitor apicularen A through an oxidative cyclization protocol. In this reaction regioselective cleavage of one homobenzylic ether in the presence of another homobenzylic ether is achieved by selectively weakening one carbon-carbon σ-bond through substitution. This work demonstrates that oxidative fragmentation reactions can be used to generate stable cations selectively, even in the presence of other readily oxidized groups, provided that bond cleavage is sufficiently rapid following oxidation.
Key words
acetals - cations - cyclizations - electron transfer - oxidations
