dialkyl acetylenedicarboxylates; and (c) pseudo three-component reaction of anilines and methyl propiolate under solvent-free conditions at 100°C. The promoter of these annulation processes is a novel inorganic–organic core–shell that was obtained from silicated titanomagnetite, tryptophan amino acid, and ethyl iodide. The tryptophan embedded on the silicated titanomagnetite core (Fe3-xTixO4-SiO2) followed
取代喹诺酮-2-羧酸酯库(4,6-二取代喹诺酮-2-羧酸酯、6-取代喹啉二烷基-2,4-二羧酸酯和6-取代4-[2-甲氧基-2-氧乙基]喹啉- 2-甲基羧酸盐)是通过不同范围的一锅一步 MCRs 获得的,例如 (a) 芳香胺、乙炔二羧酸二烷基酯和末端烯烃/酮的三组分反应;(b) 苯胺与乙炔二羧酸二烷基酯的拟三组分反应;(c) 苯胺和丙炔酸甲酯在 100°C 无溶剂条件下的假三组分反应。这些环化过程的促进剂是一种新型的无机-有机核-壳,它是从硅化钛磁铁矿、色氨酸氨基酸和碘乙烷中获得的。嵌入在硅化钛磁铁矿核上的色氨酸(Fe3-x Ti x O 4 -SiO 2 ),随后用乙基碘烷基化,随后导致原位制备碘化三乙基色氨酸离子液体(TrpEt 3 + I - )。最终的纳米杂化物(Fe 3-x Ti x O 4 -SiO 2 @TrpEt 3 + I -) 通过场发射扫描电子显微镜、EDAX、FT-IR、TGA/DTG、振动样品磁强计和
