  • Selective syntheses of 2H-1,3-oxazines and 1H-pyrrol-3(2H)-ones via temperature-dependent Rh(II)-carbenoid-mediated 2H-azirine-ring expansion

    the reaction at elevated temperatures. According to DFT-calculations a one-atom oxazine ring contraction involving ring-opening to a 2-azabuta-1,3-diene intermediate, followed by a 1,5- and 1,2-prototropic shift leads to the consecutive formation of imidoylketene and azomethine ylide, which then further undergo cyclization to the pyrrole derivative.

  • Rh2(OAc)4-catalyzed reaction of α-diazocarbonyl compounds with 2-carbonyl-substituted 2H-azirines
    作者:Kirill V. Zavyalov、Mikail S. Novikov、Alexander F. Khlebnikov、Dmitry S. Yufit
    DOI:10.1016/j.tet.2013.04.022
    日期:2013.6
    The Rh-2(OAc)(4)-catalyzed reaction of 2H-azirine-2-carbaldehydes with dimethyl diazomalonate proceeds via azirinium ylide formation, isomerization to 2-azabuta-1,3-dienes followed by 1,6-pi-electrocyclization to give 2H-1,3-oxazines. According to DFT-calculations ring opening of azirinium ylides should occur stereoselectively to give 2-azadienes with the C=C bond exclusively in the Z configuration. Changing a formyl group for an acetyl group in the azirine leads to a lowering of stereoselectivity and the formation of azadienes with an E configuration of the C=C bond was observed. The reaction of 2-acy1-2-diazoacetates with 2H-azirine-2-carbaldehydes proceeds similarly, but the 2-acetyl-substituted 2H-1,3-oxazines formed are unstable under chromatographic purification and rearrange easily into pyrrole derivatives.
