Allenephosphoramides were prepared from propargyl alcohols and diethyl arylphosphoramides using Yb(OTf)3 as catalyst. In the presence of iodine, 4,9-dihydro-2H-benzo[f]isoindole derivatives could be efficiently constructed from the same two starting materials in a single step.
使用Yb(OTf)3作为催化剂,由炔丙醇和二乙基芳基磷酰胺制备烯丙基磷酰胺。在碘的存在下,可以在同一步骤中由相同的两种原料有效地构建4,9-二氢-2 H-苯并[ f ]异吲哚衍生物。
