Formal [3+3]-cycloaddition of 3-methyl-5,6-dihydro-4H-1,2-oxazine-N-oxides with cyclopropane dicarboxylates under hyperbaric conditions

[Display omitted] The [3+3]-cycloaddition of cyclopropane dicarboxylates with 3-methyl-5,6-dihydro-4H-1,2-oxazine-N-oxides promoted by Yb(OTf)3 under hyperbaric conditions is described. The substrates scope and reaction mechanism are discussed.
