4344-84-7, Name is 5-Oxotetrahydrofuran-2-carboxylic acid, belongs to tetrahydrofurans compound, is a common compound. SDS of cas: 4344-84-7In an article, once mentioned the new application about 4344-84-7.
The synthesis is described of a porphyrin alcohol (22) which has a structure very similar to that of porphyrin a (2).The model porphyrin was resolved by separation of its camphanate esters.Ozonolysis of the 2-nitrobenzoate of each enantiomer in tritiated form gave a derivative of 2-hydroxypentadioic acid whose configuration was determined by dilution analysis.It is demonstrated that correlation of the stereochemistry of porphyrin a with that of the model (22) will be possible by means of the (1)H and (19)F n.m.r. spectra of the corresponding esters with (-)-3,3,3-trifluoro-2-methoxy-2-phenylpropanoic acid.
