  Synthesis and reactivity of β-phenylselanyl α-oxoesters

  摘要：

  beta-Phenylselanyl alpha-oxoesters 2 were prepared by N-phenylselanyl morpholine treatment of alpha-oxoesters 1, oxidized into beta-unsaturated alpha-oxoesters 5 and subjected to the Wittig-Horner olefination. The diethyl (1-phenylselanylalkyl)maleates 6 have led, after [2,3]sigmatropic rearrangement of the corresponding selenoxides, to the diethyl 3-alkylidene-2-hydroxysuccinates 7. The 2-(t-butoxycarbonylamino)-3-alkylidenesuccinates 8 were prepared in a similar way. The decomposition of halo-adducts derived from compounds 6 has allowed the synthesis of the diethyl 3-alkylidene-2-halosuccinates 9 and 10. (C) 1997 Elsevier Science Ltd.

  The present invention relates to a method for reducing the production of methane emanating from the digestive activities of a ruminant by using as active compound at least one azido alkanoic acid and/or derivative thereof, which is administrated to the animal together with the feed. The invention also relates to the use of these ingredients in feed and feed additives such as premix, concentrates and total mixedration (TMR) or in the form of a bolus.
