Graphical Abstract

The Swern oxidation is ideal for the transformation of strained cis-1,2-cyclo-pentanediols such as 1 to α-diketones such as 2. Compound 2, the valene of o-benzoquinone, is thus readily accessible. Its synthetic potential is demonstrated by the construction of other valenes, such as 3 (reaction of 2 with diaminomaleonitrile).
