Abstract

(1R)-2endo-Bromoacetyl-1,7,7-trimethylbicyclo[2.2.1]heptan-2-ol (endo-2-bromoacetylisoborneol)4 and its trimethylsilyl ether 3 are presented as efficient reagents for the asymmetric Darzens reaction. From the α,β-epoxy ketone adducts the chiral inductor camphor is removed, by treatment with ceric(IV) ammonium nitrate, to yield the corresponding epoxy acids which are isolated as their dicyclohexylammonium salts.
