摘要:
Amine derivatives of benzoylbenzoic acid, benzoylbenzoic acid esters and salts were prepared, which are suitable as photo initiators for UV & LED curable compositions. The derivatives are compounds of Formula I, Ia, and II wherein R1, R1a, R2, R3, n and r are as defined herein.
摘要:
The present invention concerns a new process for the synthesis of aminaphtone, which makes use of non-toxic solvents and reagents, under mild reaction and temperature conditions. The aminaphtone obtained with the method of the present invention also has a purity of at least 98% in weight. The method comprises the following steps: a) epoxidating menadione 1 to provide epoxide 2, b) acidifying epoxide 2 to provide hydroxynaphthoquinone 3, c) esterifying between hydroxynaphthoquinone 3 and 4-aminobenzoyl chloride to obtain compound 4, and d) reducing compound 4 in the presence of a reducing agent in water to obtain aminaphtone.
摘要:
The present invention relates to 1H-Quinazoline-2,4-diones of formula (I) wherein R1 and R2 are as defined in the specification, their preparation, their use as pharmaceuticals, and pharmaceutical compositions containing them. Further, intermediates for the manufacture of compounds of formula (I) are and combinations comprising compounds of formula (I) are disclosed.
摘要:
The anthranilic acid derivative or the salt thereof represented by the general formula wherein R1 and R2 are hydrogen atom, or the like; R3 is a phenyl, cycloalkyl or bicyclic heterocyclic group which may be substituted, or the like; R4 is a phenyl, cycloalkyl or pyridyl group which may be substituted, or the like; X1 is an alkylene or alkenylene group which may be substituted or a bond; X2 is the general formula —X3—X4— or —X4—X3—, wherein X3 is a sulfur atom, an imino group or a bond, or the like; X4 means an alkylene or alkenylene group which may be substituted or a bond; is useful for a remedy such as rheumatoid arthritis, osteoarthritis and carcinoma, because it shows MMP—13 production inhibitory effect.
