Oxidation of spiroketones with DDQ - Synthesis of tropone derivatives and DDHQ diesters

Oxidation of spiroketones 3a-f with DDQ in dry benzene gave tropone derivatives 4a-f and DDHQ esters 5a-f (cis-cis isomer 6a-f, trans-trans isomer 7a-f). While the aryl substituted spirokeone 17a gave a 2:1 mixture of 19a and the corresponding trans-trans

Oxidations with 2,3-dichloro-5-, 6-dicyano-p-benzoquinone (DDQ): Part III - Oxidation of spironaphthalenols - Synthesis of naphtho[2, 1-b]furan derivatives

Oxidation of the spironaphthalenols (3a-c and 4) with DDQ gives the naphtho[2, 2-b]furan derivatives (5a-c and 6a-c). The spectral properties (IR and NMR) of these compounds are discussed.
