title: Preparation of allenephosphoramide and its utility in the preparation of 4,9-dihydro-2h-benzo[f]isoindoles.
abstract: 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.
