Fluorinated organic molecules are pervasive within the pharmaceutical and agrochemical industries due to the range of structural and physicochemical properties that fluorine imparts. To date, the most abundant methods for the synthesis of the aryl CF2-functionality have relied on the deoxyfluorination of ketones and aldehydes using expensive and poorly atom economical reagents. Here, we report a general
Disclosed are novel pyrrole derivatives, a process for their manufacture, pharmaceutical compositions containing such compounds and the use of such compounds in the treatment of HIV mediated diseases.
Reaction of N-fluoropyridinium fluoride with isonitriles and diazo compounds: a one-pot synthesis of (pyridin-2-yl)-1H-1,2,3-triazoles

Reaction of N-fluoropyridiniumfluoride generated in situ with a series of isonitriles and diazo compounds led to the formation of the corresponding (pyridine-2-yl)-1H-1,2,3-triazoles in good yields (37–59%). Best outcome was consistently achieved with both aromatic isonitriles and stabilized diazo derivatives. The proposed reaction mechanism involves the intermediate formation of a highly reactive
原位生成的N-氟吡啶鎓氟化物与一系列异腈和重氮化合物的反应导致形成了相应的(吡啶-2-基)-1 H -1,2,3-三唑,收率很高(37-59% )。芳族异腈和稳定的重氮衍生物均能始终达到最佳结果。所提出的反应机理涉及高反应性卡宾物质的中间形成。

The invention comprises novel aminopiperidine derivatives, a process for their manufacture, pharmaceutical compositions and the use of such compounds in medicine. In particular, the compounds of formula I prevent the human immunodeficiency virus (HIV) from entering cells by blocking interaction of the viral envelope protein gp120 with a chemokine receptor on the cell surface. The compounds of this invention may be advantageously used as therapeutic agents for the treatment of diseases mediated by the human immunodeficiency virus (HIV), either alone or in combination with other inhibitors of HIV viral replication or with pharmacoenhancers.
