标 题:Oxonol compound, light-sensitive material and process for the synthesis of oxonol compound
发明人：NISHIGAKI JUNJI; DEGUCHI YASUAKI
权利人:FUJI PHOTO FILM CO LTD
摘要:An oxonol compound is represented by the following formula (I): in which Z is an atomic group that forms a cyclic amide ring; each of W1 and W2 independently is an atomic group that forms an acidic nucleus ring; and M is a cation. Other oxonol compounds, a light-sensitive material containing an oxonol compound and a process for the synthesis of an oxonol compound are also disclosed.

标题 :Process for preparing alcohols from olefins and synthesis gas
发明人：KNIFTON JOHN F; GRIGSBY JR ROBERT A
权利人:TEXACO INC
摘要:This invention concerns an improved process of preparing predominantly linear alcohols which comprises the steps of contacting a mixture of terminal and/or internal olefins and synthesis gas with a catalyst system comprising a ruthenium-containing compound in conjunction with one or more tertiary amine promoters, dispersed in a low melting quaternary phosphonium salt and heating said resultant reaction mixture under a pressure of 100 psi or greater at a temperature of at least 50 DEG C. for a sufficient time to produce said alcohols.

标题 :Alpha 1a adrenergic receptor antagonists
发明人：SIDLER DANIEL R; LARSEN ROBERT D; LI WENJIE
权利人:MERCK & CO INC
摘要:This invention relates to crystalline pharmaceutically acceptable salts of an alpha 1a adrenergic receptor antagonist, Compound A, which are useful in the treatment of benign prostatic hyperplasia. Pharmaceutical compositions employing the crystalline salts, and processes for making and using the crystalline salts and pharmaceutical compositions of Compound A are also disclosed. This invention further relates to a process for obtaining enantiomerically pure intermediate useful for the synthesis of end product alpha 1a adrenergic receptor antagonists. The end product compounds are useful for the treatment of benign prostatic hyperplasia and for relaxing lower urinary tract tissue. The invention also relates to a process for preparing a class of dihydropyrimidinone compounds of which Compound A is a member, wherein the process involves deprotonating a dihydropyrimidinone compound and then coupling the deprotonated derivative with a primary amine.
