On August 18, 1994, Maier, Franz Karl; Ebert, Wolfgang; Lee-Vaupel, Mary; Gries, Heinz; Conrad, Juergen published a patent.Name: Methyl 2-(3-formylphenyl)acetate The title of the patent was Preparation of meso-tetraphenylporphyrin complexes as diagnostic and therapeutic agents. And the patent contained the following:
Title complexes comprising I [R1 = VCOA, VSO2A, VP(O)A2, NECH2COA; A = OH, OR4, NR5R6; E = acyl, alkylsulfonyl, carboxyalkyl, etc.; R2 = groups cited for R1 and R3; R3 = H, halo, alky; R4 = alkyl, CH2Ph; R5,R6 = H, hydrocarbyl, aryl(alkyl); NR5R6 = heterocyclyl; V = (un)substituted alkylene] and an ion of elements having Z = 21-32, 38, 39, 42-51, and 58-83 were prepared Thus, Mn3+ {5,10,15,20-tetrakis[4-(carboxymethoxy)phenyl]porphyrin} chloride was prepared in 3 steps from 5,10,15,20-tetrakis(4-hydroxyphenyl)porphyrin. Physiol. compatibility and relaxivity data for 2 I were given. The experimental process involved the reaction of Methyl 2-(3-formylphenyl)acetate(cas: 142327-44-4).Name: Methyl 2-(3-formylphenyl)acetate
The Article related to mesotetraphenylporphyrin complex preparation diagnostic therapeutic, Physical Organic Chemistry: Oxidation-Reduction, Including Dehydrogenation and Hydrogenolysis and other aspects.Name: Methyl 2-(3-formylphenyl)acetate
