of α,β-unsaturated methyl ketone/nitro compounds from benzylic amines through an oxidation–aldol/Henry reaction is reported. The reaction proceeded well by using MCPBA as oxidant and CuCl2·2H2O as catalyst. A variety of functionalized α,β-unsaturated methyl ketone/nitro compounds were assembled in moderate yields by application of this catalytic one-pot reaction.
A novel series of C3-functionalized oxindoles, 3-(2-oxo-4-phenylbut-3-en-1-ylidene) indolin-2-ones as potential Pim-1 kinase inhibitors, were designed, synthesized and investigated for inhibition of human cancer-cell proliferation.

tumors. In general, Mannich bases containing olefinic bonds were more cytotoxic than the analogues without this functional group, while the piperidines 9 and 11 were more potent than the acyclic analogues 1 and 4, respectively. Correlations were noted between various physicochemical constants in the aryl rings and cytotoxicity. Compound 9d displayed promising in vivo activity against colon cancers. This
完成了一系列1-芳基-5-二乙基氨基-1-戊-3-酮盐酸盐1和1-芳基-3-二乙基氨基-1-丙烷盐酸盐4的合成。尝试制备相应的双(5-芳基-3-氧代-4-戊烯基)乙胺盐酸盐2和双(3-芳基-3-氧代丙基)乙胺盐酸盐5导致形成一系列4-(β-芳基乙烯基) )-3-(β-芳基乙烯基酮)-1-乙基-4-哌啶醇盐酸盐9和4-芳基-3-芳基酮-1-乙基-4-哌啶醇盐酸盐11盐10和12。这些化合物的结构通过1 H NMR光谱确定,并通过代表性分子的X射线晶体学证实。大多数化合物对鼠P388和L1210细胞以及人类肿瘤均表现出明显的细胞毒性。通常,含有烯键的曼尼希碱比没有该官能团的类似物具有更高的细胞毒性,而哌啶9和11分别比无环类似物1和4更有效。注意到芳基环中各种物理化学常数与细胞毒性之间的相关性。化合物9d显示出抗结肠癌的有希望的体内活性。这项研究表明,哌啶9和11构成了新型的细胞毒剂。化合物9
