资源简介：
The
diastereoconvergent synthesis of spirocyclic endoperoxides
using a Meldrum’s acid scaffold has been accomplished by employing
readily available feedstock chemicals. Site selective C–H oxidation
of the bis(β-dicarbonyl) substrates was performed using elemental
oxygen as the stoichiometric oxidant and a commercial Cu(II) catalyst.
Sequential hydrogenolysis and ionic reduction of these endoperoxides
provided fully substituted tetrahydrofurans in high yields and diastereoselectivity.
