Okamoto, Ryuichi; Okazaki, Eri; Noguchi, Keiichi; Tanaka, Ken published the artcile< Rhodium-catalyzed olefin isomerization/enantioselective intramolecular Alder-ene reaction cascade>, HPLC of Formula: 139139-86-9, the main research area is dihydrobenzofuran dihydronaphthofuran derivative enantioselective synthesis; enyne olefin isomerization Alder ene reaction Rh chiral ligand.
The olefin isomerization/enantioselective intramol. Alder-ene reaction cascade was achieved by using a cationic rhodium(I)/(R)-BINAP complex as a catalyst. A variety of substituted dihydrobenzofurans e. g., I and dihydronaphthofurans e. g., II were obtained from phenol- or naphthol-linked 1,7-enynes, resp., with good yields and ee values.
