CAS: 90897-92-0; Magnesium,1,2-Difluorobenzene-5-Ide,Bromide

该化合物是有机合成中常用的一种Grignard试剂,用于将3,4-二氟苯基组引入目标分子.溶液的标准化浓度(0.50M)确保了持续反应性,而2-METHF(2-甲基氢呋喃)则作为传统醚溶剂的绿色替代品,提供更好的稳定性和减少过氧化形成.这种试剂在制药和农用化学应用中特别有用,选择性氟化可以加强生物活动.其现用配方尽量减少与对湿度敏感的红色试剂相关的风险.建议在惰性大气中适当储存以保持再活动性.始终要评估与使用前的反应条件的兼容性.

摘要:A synthesis method for an o-biphenyl oxazoline compound. An aryl metal compound as represent by formula II reacts with aryl oxazoline as represented by formula III to generate the o-biphenyl oxazoline compound as represented by formula I. The o-biphenyl oxazoline compound can be used for industrial preparation of o-aminobiphenyl compounds, and used for synthesizing succinate dehydrogenase inhibitor fungicides (IV) such as fluxapyroxad, bixafen, boscalid, and pyraziflumid.

标题:Alpha 1a adrenergic receptor antagonists
发明人:PATANE MICHAEL A; BOCK MARK G; NEWTON RANDALL C
权利人:MERCK & CO INC
摘要:This invention relates to certain novel compounds and derivatives thereof, their synthesis, and their use as selective alpha-1a adrenergic receptor antagonists. One application of these compounds is in the treatment of benign prostatic hyperplasia. These compounds are selective in their ability to relax smooth muscle tissue enriched in the alpha 1a receptor subtype without at the same time inducing orthostatic hypotension. One such tissue is found surrounding the urethral lining. Therefore, one utility of the instant compounds is to provide acute relief to males suffering from benign prostatic hyperplasia, by permitting less hindered urine flow. Another utility of the instant compounds is provided by combination with a human 5-alpha reductase inhibitory compound, such that both acute and chronic relief from the effects of benign prostatic hyperplasia are achieved.
