Palladium-Catalyzed C(sp3)-H Nitrooxylation with tert-Butyl Nitrite and Molecular Oxygen

Herein, we report a Pd(II)-catalyzed nitrooxylation of unactivated methyl C(sp3)-H bonds using commercial available and easily manageable tert-butyl nitrite as the precursor of ONO2 radical under aerobic conditions. Environmentally benign molecular oxygen is used to initiate the generation of active radical reactant; it is also used as the terminal oxidant. A broad range of nitrooxylated aliphatic carboxamides were prepared in moderate to good yields under mild conditions.

Developing Pd(II) catalyzed double sp3 C-H alkoxylation for synthesis of symmetric and unsymmetric acetals

An effective Pd(II) catalyzed double unactivated C(sp3)-H alkoxylation has been developed to prepare both symmetric and unsymmetric acetals. This new reaction demonstrates good functional group tolerance, excellent reactivity, and high yields. A variety of novel acetals can be readily accessed via this new method. (Chemical Equation Presented).

Carbamoyl derivatives

The present invention concerns novel carbamoyl derivatives of formula I, set out herein, which antagonize the pharmacological actions of one or more of the arachidonic acid metabolites known as leukotrienes, making them useful whenever such antagonism is desired, such as in the treatment of those diseases in which leukotrienes are implicated, for example, in the treatment of allergic or inflammatory diseases, or of endotoxic or traumatic shock conditions. The invention also provides pharmaceutical compositions containing the novel derivatives for use in such treatments, methods for their use and processes and intermediates for the manufacture of the novel derivatives.
