The first synthesis of some spiro[2,3-dihydro-2,2-dimethylbenzofuran-3,1'- cyclopropanes] through, Mo(CO)6 catalyzed, one pot claisen rearrangement-cyclization reaction of 2-cyclopropylidene-aryloxy alkanes
Mo(CO)6 effectively transforms the cyclopropylidene aryloxy derivatives 2a-e,g into the previously unknown spiro[2,3-dihydro-2,2- dimethylbenzofuran-3,1'-cyclopropanes] 3a-e,g.
