Facile Nafion-H catalyzed isomerization of glycidic esters to α- hydroxy-β,γ-unsaturated esters is reported. These compounds are useful synthetic intermediates. Application in the synthesis of a trifluoromethylated vinylic epoxide is demonstrated.

A series of 3-(nosyloxy)-2-keto esters 7a-j were prepared from the corresponding α-keto esters by conversion to the trimethylsilyl enol ether and reaction with p-nitrobenzenesulfonyl peroxide. Conversion of these materials to 1,2,3-trifunctionalized compounds is described, and comparison of their properties with isomeric 2-(nosyloxy)-3-keto esters is discussed.
Synthesis and reactivity of β-phenylselanyl α-oxoesters

β-Phenylsetanyl α-oxoesters 2 were prepared by N-phenylselanyl morpholine treatment of α-oxoesters 1, oxidized into β-unsaturated α- oxoesters 5 and subjected to the Wittig-Horner olefination. The diethyl (l- phenylselanylalkyl)maleates 6 have led, after [2,3]sigmatropic rearrangement of the corrsponding selenoxides to the diethyl 3-alkylidene-2- hydroxysuccinates 7. The 2-(1-butoxycarbonylamino)-3-alkylidenesuccinates 8 were prepared in a similar way. The decomposition of halo-adducts derived from components 6 has the synthesis of the siethyl 3-alkylidene-2- halosuccinates 9 and 10.
