Transesterification of copper(II) acetoacetates, copper(II) trifluoroacetoacetate, and copper(II) acylpyruvates with borneol gives the copper(II) chelates of the corresponding bornyl esters in 92-95percent yields.Bornyl acetyl- and perfluoroacylpyruvates were synthesized for the first time by decomposing the respective chelates with hydrogen chloride.Bornyl acylpyruvates react with hydrazine hydrate to give 5-alkyl-3-bornyloxycarbonylpyrazoles.

Optically active N,N'-ethylenebis(α-alkoxycarbonyl-β-ketoimine) was found to be a new class of effective ligand of manganese(III) complex catalyst for the asymmetric aerobic epoxidation of simple olefins, such as 1,2-dihydronaphthalene derivatives, to afford the corresponding optically active epoxides with good to high enantioselectivities.
