On September 21, 1988, Onishi, Akiyoshi; Ishimaru, Katsutoshi published a patent.SDS of cas: 110729-26-5 The title of the patent was Preparation of 4-hydroxyphenylpropionic acids or their esters as intermediates for drugs and antioxidants. And the patent contained the following:
The title compounds I (R = H; R1 = H, CMe3; R2 = H, alkyl) (II), useful as intermediates for drugs and antioxidants, are prepared by de-tert-butylation of I (R = R1 = CMe3) (III) in the presence of acidic substances. III (R2 = Me) was refluxed with MeOH and H2SO4 in toluene for 12 h to give 60% II (R1 = R2 = H). The experimental process involved the reaction of Octadecyl 3-(3-(tert-butyl)-4-hydroxyphenyl)propanoate(cas: 110729-26-5).SDS of cas: 110729-26-5
The Article related to hydroxyphenylpropionate preparation intermediate drug antioxidant, propionate hydroxyphenyl preparation intermediate drug, phenylpropionate hydroxy preparation intermediate drug, butylhydroxyphenylpropionate debutylation acid catalyst and other aspects.SDS of cas: 110729-26-5
