标 题:Preparation of certain m-aminophenols and the use thereof for preparation of laser dyes
发明人：HAMMOND PETER R
权利人:US ENERGY
摘要:Methods are provided for making certain m-aminophenols using a sulfonation/alkali fusion procedure. The aminophenols are key intermediates in the synthesis of dyes, particularly efficient, stable dyes for laser application. Preparations of some rhodamine and phenoxazone dyes from the m-aminophenols are described.

标 题 :Hydrosoluble coumarin derivatives, their preparation and their use as an enzyme substrate or for the preparation of such substrates
发明人：CHALOM JOSEPH; GRIFFOUL CHRISTINE; TOD MICHEL; REVEILLEAU STEPHANE
权利人:EUROBIO LAB
摘要:The invention relates to hydrosoluble coumarin derivatives. These derivatives comply with the formula: (I) in which R1 represents (OCH2CH2)mOCH2R7 or (OCH(CH3)CH2)mOCH2R7 with m=1 to 30 and in which R7 can be a hydrogen atom or various groups, R2 to R6 can be different substituents, particularly substituents making it possible to introduce into the derivative an appropriate group as the enzyme substrate or for the synthesis of enzyme substrates.

标题:Method for the preparation of substituted benzene derivatives
发明人：RUHLAND THOMAS; ROTTLANDER MARIO; ANDERSEN KIM
权利人:LUNDBECK & CO AS H
摘要:A method for the preparation of selectively substituted benzene derivatives by application of solid phase synthesis is disclosed. In particular, the invention provides a novel method for the preparation of substituted benzene derivatives containing two or three groups bound to the benzene ring via nitrogen-, oxygen-, sulphur-, selenium- or carbon-carbon bonds, by application of solid phase chemistry alone or in combination with post cleavage solution phase derivatisation.
