  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.

  Reduction of α-phenylselanyl imines derived from β-phenylselanyl α-oxoesters or PhSeCl assisted nucleophilic addition of primary amines to α,β-unsaturated esters have led to β-alkylamino phenylselenides 4, 5, 12 and 13 which were cyclised into aziridines 8, 9 and 14 after selenium activation. threo-Amino selenides led stereospecifically to cis-2,3-disubstituted aziridines. Depending on the structure

  A synthesis of aziridine esters based on the cyclisation of amino selanyl esters induced by the selanyl group activation was developed with either the Meerwein salt or NBS. Two asymmetric approaches are proposed: the diastereoselective reductions of α-selanyl β-iminoesters derived from α-oxoesters, which lead to cis chiral aziridine esters 6 and 6′; and the diastereoselective conjugate additions of
