标题 :An improved process for the preparation of tetrahydroisoquinoline compounds
发明人：DALVI MAHESH BHAGOJI; KENNY RAJESH SHASHIKANT; PATIL AJIT AAPPA; PALKAR TUSHAR TANAJI
权利人:NEON LABORATORIES LTD
摘要:The present invention discloses an improved process for preparation of substantially pure pentamethylene bis(1-(3,4-dimethoxybenzyl)-3,4-dihydro-6,7- dimethoxy-1H-isoquinoline-2-propionate), a compound of formula I and its acid addition salts in good yields. Pentamethylene bis(1-(3,4-dimethoxybenzyl)-3,4- dihydro-6,7-dimethoxy-1H-isoquinoline-2-propionate) or its acid addition salts is the key intermediate for the synthesis of a non-depolarizing neuromuscular-blocking drugs. The process can also be used for the synthesis of various tetrahydroisoquinoline derivatives.

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.

标题 :Method of preparing a polymeric coating composition
摘要:A method of preparing a storage-stable one-part reactive liquid thermal curing polymeric coating composition from an isocyanate-functional polymeric compound which has a substantial portion of its isocyanate groups masked with an isocvanate masking agent, and a crosslinking agent which is substantially insoluble in aprotic solvents. These liquid compositions are homogeneous even when free of solvents. Preferably the crosslinking agent is a crystalline polyol. The method involves the synthesis of a solubilizing oligomer which is formed by the partial reaction of the crosslinking agent and the unmasked isocyanate-functional polymeric compound. The thermal curing of these compositions results in polymeric coatings which possess superior physical properties. These cured coatings are particularly useful in the manufacture of retroreflective sheeting.

标 题:Process for phenol alkylthiolation and its application to the synthesis of 4-acyl-2-alkylthiophenols
发明人：VOTTERO CATHERINE; LABAT YVES; POIRIER JEAN-MARIE
权利人:ELF AQUITAINE
摘要:The invention relates to the preparation of alkylthiophenols by reaction of a dialkyl disulphide with a phenol. n In the process according to the invention, the reaction is carried out in the presence of aluminum chloride or of ferric chloride in a solvent of the alkylbenzene type or, soley in the case of methylthiolation, in an excess of dimethyl disulphide. n This process makes it possible, in particular to obtain, with a selectivity and in a yield which are excellent, 2-alkylthiophenols which may then be converted into 4-acyl-2-alkylthiophenols by means of a reaction at a temperature ranging from 40° to 100° C. with a complex BF 3 :2RCOOH where R denotes an alkyl or propenyl radical, in a proportion of 10 to 15 moles of complex per mole of 2-alkylthiophenol.
