Rh2(II)-Catalyzed Ester Migration to Afford 3H-Indoles from Trisubstituted Styryl Azides
摘要:
Rh-2(II)-Complexes trigger the formation of 3H-indoles from ortho-alkenyl substituted aryl azides. This reaction occurs through a 4 pi-electron-5-atom electrocyclization of the rhodium N-aryl nitrene followed by a [1,2]-migration to afford only 3H-indoles. The selectivity of the migration is dependent on the identity of the beta-styryl substituent.

palladium-catalyzed hydroalkylation, but rather served as a source of HCl, which presumably catalyzes enolization of the ketone. Identification of HCl as the active promoter of palladium-catalyzed hydroalkylation led to the development of an effective protocol for the hydroalkylation of alkyl 3-butenyl ketones that employed sub-stoichiometric amounts of 2, HCl, and CuCl2 in a sealed tube at 70 degrees C.

Depending on the substitution pattern of cyclopropylketones, the photochemically induced electron transfer of tertiary amines to cyclopropylketones leads either to the formation of 3-substituted cycloalkanones or to ring expanded products.

Soluble guanylate cyclase (sGC), the endogenous receptor for nitric oxide (NO), has been implicated in several diseases associated with oxidative stress. In a pathological oxidative environment, the heme group of sGC can be oxidized becoming unresponsive to NO leading to a loss in the ability to catalyze the production of cGMP. Recently a dysfunctional sGC/NO/cGMP pathway has been implicated in contributing
可溶性鸟苷酸环化酶(sGC)是一氧化氮(NO)的内源性受体,与多种与氧化应激有关的疾病有关。在病理性氧化环境中,sGC的血红素基团可被氧化而变得对NO无响应,从而导致催化cGMP产生的能力下降。最近,功能异常的sGC / NO / cGMP途径与青光眼相关的眼内压升高有关。在这里,我们描述了专门设计用于局部眼部给药的分子的发现,该分子可以激活氧化的sGC,恢复催化cGMP产生的能力。这些努力最终导致了化合物(+)-23的鉴定,可在单次局部滴眼后24小时内强烈降低眼内压升高的食蟹猴模型中的眼内压,已被选择用于临床评估。
