摘要:
Cured epoxide resins are widespread on account of their excellent mechanical and chemical properties. Usually, epoxide resins based on bisphenol A or bisphenol F diglycidyl ethers are used, although these are problematic for many areas on account of their endocrine effect. The present invention relates to glycidyl ethers of divinylbenzene-based diols and/or polyols and curable epoxide resin compositions based thereon as alternatives to the bisphenol A or bisphenol F diglycidyl ethers or the epoxide resin compositions based thereon.
摘要:
Disclosed is a method for producing an alcohol from a lactone or a carboxylic acid ester, which enables to produce an alcohol from a lactone or a carboxylic acid ester under relatively mild conditions with high yield and high catalytic efficiency. This method also enables to produce an optically active alcohol from an optically active lactone or an optically active carboxylic acid ester. Specifically disclosed is a method for producing an alcohol by hydrogen reducing a lactone or a carboxylic acid ester in the presence of a catalyst containing ruthenium and a phosphine compound represented by the following general formula (1):
wherein R 1 represents a spacer; R 2 , R 3 , R 4 , R 5 , R 6 and R 7 independently represent a hydrogen atom, an alkyl group having 1-12 carbon atoms, an aryl group or a heterocyclic group; and R 8 , R 9 , R 10 , R 11 , R 12 and R 13 independently represent an alkyl group having 1-12 carbon atoms, an aryl group or a heterocyclic group.

The invention is a process of using, as a reducing agent, a 12CaO·7Al 2 O 3 electride containing electrons in a number of 10 19 cm -3 or more and 2.3 × 10 21 cm -3 or less in its cages to subject a carbonyl compound to reductive coupling in a solvent, thereby synthesizing a diol or polydiol. The invention is also a process of reducing a ketone compound in a solvent, thereby synthesizing a secondary alcohol or diketone compound. According to the process of the invention, it is possible to synthesize a diol or polydiol, or a secondary alcohol or diketone compound through simple operations in a short period without using an expensive and harmful metal hydride or metal salt nor limiting the atmosphere for the synthesis to an inert gas atmosphere as in conventional processes.

摘要:
The present invention pertains to certain ketones and reduced ketones and derivatives thereof which, inter alia, inhibit osteoclast survival, formation, and/or activity; and/or inhibit bone resorption, and more particularly to compounds of the formulae: (1) (2) wherein: Ar1 is independently a biphenyl, phenanthryl, fluorenyl, or carbazolyl, and is optionally substituted; Ralk is independently a C2-10alkylene group, and is optionally substituted; -ORO, if present, is independently -OH or -ORK; -ORK, if present, is independently selected from: -O-RK1; -O-C(=O)RK2; -O-C(=O)ORK3; -O-S(=O)2ORK4; Q is independently -OH or -OROT; wherein: -OROT, if present, is independently selected from: -O-RE1; -O-C(=O)-RE2; -O-C(=O)-O-RE3; -O-C(=O)-O-SO3RE4; -O-C(=O)-O-(CH2)n-COORE5; -O-C(=O)-(CH2)n-NRN1RN2; -O-C(=O)-(CH2)n-NH-C(=O)RE6; -O-C(=O)-(CH2)n-C(=O)-NRN3RN4; -O-P(=O)(ORE7)(ORE8); -O-RPA; RPA, if present, is an organic group which incorporates a phosphonic acid group; with the proviso that if -OROT is -O-RE1, then RE1 is not a phenyl group substituted with a sulfonyl group; and pharmaceutically acceptable salts, solvates, amides, esters, ethers, chemically protected forms, or prodrugs thereof. The present invention also pertains to pharmaceutical compositions comprising such compounds, and the use of such compounds and compositions, both in vitro and in vivo, to inhibit osteoclast survival, formation, and/or activity, and to inhibit conditions mediated by osteoclasts and/or characterised by bone resorption, in the treatment of bone disorders such as osteoporosis, rheumatoid arthritis, cancer associated bone disease, Paget's disease, aseptic loosening of prosthetic implants, and the like; and/or in the treatment of conditions associated with inflammation or activation of the immune system.
