On January 22, 2021, Li, Yanxiong; Xu, Liang; Meng, Faming; Yu, Yonghai published a patent.Recommanded Product: 65645-88-7 The title of the patent was Preparation of (S)-1-(3-ethoxy-4-methoxyphenyl)-2-(methylsulfonyl)ethylamine and chiral catalyst thereof. And the patent contained the following:
The invention relates to preparation of (S)-1-(3-ethoxy-4-methoxyphenyl)-2-(methylsulfonyl)ethylamine and chiral catalyst thereof, which has the advantages of high yield and simple method, low cost, environmentally friendly and safety. The (S)-1-(3-ethoxy-4-methoxyphenyl)-2-(methylsulfonyl)ethylamine was prepared by the following steps: mixing 1-(3-ethoxy-4-methoxy Phenyl)-2-(methylsulfonyl)vinylamine, chiral catalyst I, acid and solvent, performing isomerization to obtain the final product; where R=hydrogen atom, C1-20 linear alkyl, C3-20 branched chain alkyl, C3-10 cycloalkyl, C3-10 heterocyclyl, C1-20 alkoxy, trifluoromethyl, halogen, amino, cyano, hydroxyl, nitro, ester, amide, substituted or unsubstituted C6-20 aryl, substituted or unsubstituted C5-20 heteroaryl. The experimental process involved the reaction of (S)-2-Hydroxy-N-methyl-2-phenylacetamide(cas: 65645-88-7).Recommanded Product: 65645-88-7
The Article related to preparation ethoxymethoxyphenylmethylsulfonylethylamine chiral catalyst isomerization, Benzene, Its Derivatives, and Condensed Benzenoid Compounds: Phenols, Thiophenols, and Derivatives Including Phenol and Thiophenol Ethers and Esters and other aspects.Recommanded Product: 65645-88-7
