Chemoselective Synthesis of Novel Heterocyclic [3.3.3]Pro- pellane Derivatives via a One-pot Three-component Reaction

引用

Chinese Journal of Chemistry 2017年第9期35卷 1463-1468页

作者： Jing Wang Hongzhi Liu Ren Wen Jie Li Songlei Zhu Department of Chemistry School of Pharmacy Xuzhou Medical University Xuzhou Jiangsu 221004 China Zhengda Tianqing Pharmaceutical Group Co. LTD Lianyungang Jiangsu 222062 China

A highly chemoselective method for the synthesis of heterocyclic [3.3.3]propellane derivatives was developed via sequential three-component reactions of acenaphthenequinone, malononitrile/cyanoacetate and a variety of 1,3-dicarbonyl compounds under mild conditions in ethanol. A plausible mechanism for this type of reaction was proposed. The value of this method was highlighted by its high selectivity, simple procedures, and good yields.

Synthesis, Crystal Structure and Antimicrobial Activity of (E)-ethyl-4-(2-oxoacenaphthylen-1(2<i>H</i>)-ylideneamino) benzoate

引用

Journal of Crystallization Process and Technology 2013年第2期3卷 69-73页

作者： Yi-Chen Chan Abdussalam Salhin Mohamed Ali Melati Khairuddean Baharuddin Salleh School of Biological Sciences Universiti Sains Malaysia Penang Malaysia School of Chemical Sciences Universiti Sains Malaysia Penang Malaysia

A Schiff base, (E)-ethyl-4-(2-oxoacenaphthylen-1(2H)-ylideneamino)benzoate, (E4AB) had been synthesized in good yield by the acid-catalyzed condensation reaction of acenaphthenequinone and ethyl-4-aminobenzoate in methanolic solution. The synthesized compound was elucidated by elemental analysis (CHN), FTIR, 1H-NMR, 13C-NMR and single crystal X-ray diffraction. E4AB crystallized in the monoclinic crystal system with space group P21/c, Z = 4, V = 1569.3(2) ?3 and unit cell parameters a = 9.1589(8) , b = 21.2003(17)?, c =8.4502(7) ?, β= 106.972(2)°. The crystal structure of the compound is stabilized by intermolecular C-H···O hydrogen bonds and weak intermolecular π···π interactions. The title compound had been tested for the antimicrobial activity against Bacillus subtilis (B. subtilis), Enterobacter and Fusarium oxysporum f. sp. Cubense (Foc) by disc-diffusion method. E4AB is relatively active against Foc which is a pathogen that cause Wilt disease (also well known as Panama disease) in banana plantation.
