    Morita-Baylis-Hillman acetates and α-bromonitroalkenes have been employed in cascade reactions with lawsone and 2-aminonaphthoquinone for the one-pot synthesis of heterocycle fused quinonoid compounds. The reactions reported here utilized the 1,3-binucleophilic potential of hydroxy- and aminonaphthoquinones and the 1,2/1,3-bielectrophilic potential of bromonitroalkenes and Morita-Baylis-Hillman acetates
    Morita-Baylis-Hillman乙酸盐和α-溴硝基烯烃已用于与Lawone和2-氨基萘醌的级联反应,用于一锅合成杂环稠合的醌类化合物。此处报道的反应利用羟基和氨基萘醌的1,3-双亲核势以及溴硝基烯烃和Morita-Baylis-Hillman乙酸酯的1,2 / 1,3-双亲电势来合成吡咯和呋喃稠合的萘醌。对合成的化合物针对HCT-116(人类结肠癌细胞),PC3(人类前列腺癌细胞),HL-60(人类早幼粒细胞白血病细胞),SF295(人类胶质母细胞瘤细胞)和NCI-H460(人类肺癌细胞)进行了评估。并显示出抗肿瘤活性,IC50值低至<2μM。还针对OVCAR-8(卵巢)评估了选定的化合物,MX-1(乳腺癌)和JURKAT(白血病)细胞系。还使用非肿瘤细胞测定了评价的醌类的细胞毒性潜力,例如外周血单核(PBMC)和L929细胞。

    The Morita–Baylis–Hillman (MBH) acetates derived from nitroalkenes and ethyl glyoxylate have been transformed in one pot at room temperature to highly fused and functionalized furans and pyrans in good to excellent yield. The reaction involves a cascade Michael–oxa-Michael addition of β-dicarbonyl compounds to the MBH acetates in the presence of an amine base such as DABCO. An unusual switching of
    源自硝基链烯和乙醛酸乙酯的Morita-Baylis-Hillman(MBH)乙酸盐已在室温下在一锅中转化为高度熔融和官能化的呋喃和吡喃,收率良好至优异。该反应涉及在胺碱(例如DABCO)存在下,将β-二羰基化合物级联反应将β-二羰基Michael-oxa-Michael加成到MBH乙酸酯中。当β-二羰基化合物从无环或六元环改为五元环时,氧杂-迈克尔加成反应的选择性从5-外-trig转变为6-内-trig。

    Pure organic: The synthesis of tetrasubstituted furans often involves transition‐metal catalysis or metal–halogen exchange reactions. A new approach to these heterocycles employs the Feist–Bénary addition–elimination process using nitroallylic acetates and 1,3‐dicarbonyls (see scheme; X=C, O).

    Cascade reactions of amidines with nitroallylic acetates and α-bromonitroalkenes provide potentially bioactive imidazoles in good to excellent yields in most cases. While 2,4-disubstituted imidazol-5-yl acetates are formed in the first case, 2,4-disubstituted imidazoles, bearing no substituent at position 5, are the products in the second case. These two series of imidazoles, viz. 2,4,5-trisubstituted
