Stereoselective Addition Reactions of Alkynes with Benzenetellurinyl Trifluoromethanesulfonate in Acetonitrile: Organotellurium-mediated One-pot Synthesis of Oxazoles from Internal Alkynes

Fukumoto, Takahiro,Aso, Yoshio,Otsubo, Tetsuo,Ogura, Fumio

, p. 1070 - 1072 (2007/10/02)

Benzenetellurinyl trifluoromethanesulfonate in conjunction with acetonitrile underwent an E-stereoselective amidotellurinylation reaction with alkynes, but the addition products from terminal alkynes tended to isomerize thermally to (Z)-β-acetamidovinyl p
