A series of novel maleimide-based inhibitors of proteinkinaseC (PKC) were designed, synthesized, and evaluated. AEB071 (1) was found to be a potent, selectiveinhibitor of classical and novel PKC isotypes. 1 is a highly efficient immunomodulator, acting via inhibition of early T cell activation. The binding mode of maleimides to PKCs, proposed by molecular modeling, was confirmed by X-ray analysis

Oxidation of α-tributylstannyl ester and amide with CeIV compounds generates α-radicals of acetic acidderivatives with the elimination of the stannyl group. The radicals thus generated react with various electron-rich olefins to give the corresponding addition products in good yield.

of the alkanoates by eliminating the stannylium ion. The thus-formed radicals react with various electron-rich olefinic compounds, such as silylenolethers, giving addition products in good yield. This method formally achieves selective cross couplingbetween alkanoates and ketones.
series of 2-amino-9-aryl-7H-pyrrolo[2,3-d]pyrimidines were designed and synthesized to target focal adhesion kinase (FAK). A number of these pyrrolopyrimides exhibited low micromolar inhibitory activities against focal adhesion kinase, and their preliminary SAR was established via systematic chemical modifications. The 2-amino-9-aryl-7H-pyrrolo[2,3-d]pyrimidines represent a new class of kinase inhibitors
Reaction of ethylα-(tributylstannyl)acetate with aryl bromides in the presence of zinc bromide or chloride and a catalytic amount of dichlorobis(tri-o-tolylphosphine)palladium was found to give ethyl arylacetates in good yields except with the aryl bromide having p-acetyl or p-nitro group.
发现在溴化锌或氯化锌和催化量的二氯双(三-邻甲苯基膦)钯存在下,α-(三丁基甲锡基)乙酸乙酯与芳基溴化物的反应以良好的收率得到芳基乙酸乙酯,除了芳基溴化物具有 p -乙酰基或对硝基。
