摘要:Methods for the synthesis of polycyclic aromatic hydrocarbons and synthesis platforms for performing such syntheses are provided. Methods and platforms are provided that allow for the synthesis of aza-polycyclic aromatic hydrocarbons by an expedient ring assembly. Methods and platforms allow for a modular approach to synthesis that provide multiple new C—C bonds in sequential pericyclic reactions, thus giving access to compounds with multiple axes of substitution.

标题 :Synthesis of 3-methyl-1,2,4-thiadiazole-5-carbohydrazide or of the methyl-d3 deuterated form thereof
发明人：HOVEYDA HAMID; DUTHEUIL GUILLAUME
权利人:OGEDA SA
摘要:The present invention relates to a method of synthesis of compound (I), wherein R1 represents methyl or methyl-d3, thus corresponding to 3-methyl-1,2,4-thiadiazole-5-carbohydrazide or to the methyl-d3 deuterated form thereof. These compounds are useful as key intermediates in the synthesis of pharmaceutical compounds, especially fezolinetant and deuterated fezolinetant.

摘要:The invention relates to the process of preparation of 2-fluoro-4-(3-methoxyphenyl)aniline (3) as an intermediate. Said intermediate 2-fluoro-4-(3-methoxyphenyl)aniline (3) is obtained in a Suzuki coupling reaction from (3-methoxyphenyl)boronic acid (1) and 4-bromo-2-fluoro-aniline (2). The invention further relates to the synthesis of vidofludimus (5) from said intermediate 2-fluoro-4-(3-methoxy-phenyl)aniline (3) and from 1-cyclopentene-1,2-dicarboxylic anhydride (4). The invention further relates to the synthesis of vidofludimus calcium (6) from said vidofludimus (5) and from a calcium salt, preferably Ca(OH)2.

权利人:MASSACHUSETTS INST TECHNOLOGY
摘要:One aspect of the present invention relates to optionally substituted halogenated benzyl halides and the like. These compounds are useful as halogenated benzyl ether-based protecting groups for a variety of functional groups. Another aspect of the present invention relates to use of said protecting groups in an orthogonal protecting group strategy for the synthesis of complex molecules that comprise a number of suitable functional groups. Another aspect of the present invention relates to saccharides bearing various arrays of protecting groups of the present invention. Another aspect of the present invention relates to a method of synthesizing an oligosaccharide or glycoconjugate, comprising the steps of: using a saccharide bearing at least one protecting group of the present invention to glycosylate a second molecule to give a product comprising said saccharide; and removing a protecting group of the present invention from said product.
