Efficient access to minimally oxidized members of the ent-kaurane and beyerane class of terpenes has been achieved by using a polyene cyclization precursor designed to directly yield oxidation at the axial C19-methyl group. Construction of the [3.2.1]bicyclic system found in the ent-kaurane skeleton was realized with two overbred intermediates. Wagner-Meerwein rearrangement of the [3.2.1]bicyclic system yields the beyerane skeleton of isosteviol. Copyright

Using regioselective cuprations (via magnesiations), various primary, secondary and tertiary aminated pyrimidine and purine derivatives were prepared by the oxidative coupling of lithium amidocuprates using chloranil. DNA and RNA units such as aminated uracil or thymine, and adenine, as well as a CDK inhibitor, purvalanol A, were all obtained under mild conditions and satisfactory yields.
