标题:Formation of chiral 4-chromanones using chiral pyrrolidines in the presence of phenols or thiophenols
发明人：LETINOIS ULLA; NETSCHER THOMAS
权利人:DSM IP ASSETS BV
摘要:The present invention relates to a synthesis of chromanones or chromanes in a stereospecific matter in view of the 2-position in the chromanone or chromane ring. It has been found that this synthesis is particularly possible in the presence of a chiral compound of formula of a specific type and of at least one phenol or thiophenol.

标 题:Novel synthesis of methyl-2-fluoroacrylate
发明人：BRUNKE JESSICA; FISCHER MICHAEL; WÖSSNER JAN STEPHAN
权利人:VIFOR INT AG
摘要:The present invention relates to novel synthesis methods of methyl 2-fluoroacrylate (MFA) which is a key precursor for the production of Veltassa® (Patiromer). The methods according to the invention are conducted by reacting an α-substituted β-hydroxy propionic acid derivative (I) via one or more intermediate steps involving one or more α-, β-substituted propionic acid derivatives (II) to obtain MFA (III).

发明人：LETINOIS ULLA; ACKERMANN STEPHAN; MEDLOCK JONATHAN ALAN; LEHMANN HAJO
权利人:DSM IP ASSETS BV
摘要:The present invention relates to a method of preparing ortho substituted phenols from 2,5-dimethylfuran and propargyl ethers in the presence of a gold(I) complex. It is particularly advantageous to use 2,5-dimethylfuran as this offers an ecological beneficial synthesis of said ortho substituted phenols.

标题 :Preparation of p-fuchsones and synthesis of p-dihydroxylated aromatic compounds therefrom
发明人：COSTANTINI MICHEL; MANAUT DANIEL; MICHELET DANIEL
权利人:RHONE POULENC CHIMIE
摘要:p-Dihydroxylated aromatic compounds are prepared via the oxidation of p-fuchsones, the latter advantageously being synthesized by reacting a phenolic compound having at least one hydrogen atom in the para-position to the hydroxyl function with a non-enolizable ketonic compound, in the presence of a catalytically effective amount of an acid catalyst and, optionally, a cocatalytically effective amount of an ionizable sulfur-containing compound.

摘要:The invention relates to improved methods of preparing dihydrothienopyrimidines of formula 1, and intermediates thereof, (I) wherein X is SO or SO 2 , preferably SO, and wherein R A , R 1 , R 2 , R 3 , R 4 and R 5 have the meanings given in the description. The methods according to this invention are more suitable for large-scale synthesis of said compounds than prior methods because the new synthetic process avoids distillation and chromatographic purification between steps and results in a higher overall yield of the desired product.
