Abstract

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 92–95 % 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.
