        abstract = {A new and efficient oxidative rearrangement of alkyl enol ethers to lactone and spiroketal esters was proposed that allowed a rapid access to the common structural subunits of natural products. Additional substrates were examined including five-and six-membered diosphenol ethers and the highly functionalized hydroxy enol ether. A procedure was also developed that provided rapid access to the desired {\ensuremath{\alpha}}-carbonyl functionalized cyclic ethers. Replacement of the tertiary hydroxy groups with a cyclic ether would establish an access to spiroacetals which are common features in biologically active natural products. Additional applications of this process are being explored towards biologically active molecules.}
