English enlightenment education exerts much effects on 3-4-year-old children and may be positively influential to future education of the children. It's concurred that there are many reasons for applying mobile multimedia into English enlightenment education. In this thesis, it's suggested that the implementation...

4-Chloro-6-methoxy-2-methyl-3-nitroquinoline (1) was synthesized from 4-methoxyaniline through three steps including Cyclization, Nitrification and Chlorination. The structure of the target product (1) was confirmed by 1H NMR and MS. This method started with cheap raw materials was of simple experimental...

Sorafenib (1) in the medical field to show the potential biological activity. Literature on the majority of tumor cells have a high biological activity, such as lymphoma, breast cancer, prostate cancer. However, some synthetic route of Sorafeni has disadvantages, such as low product yield and complicated...

Thieno[2,3-d]pyrimidine is a key intermediate in many biologically active compounds such as GDC-0941 and BKM 120. In this work, a rapid synthetic method for compound (4) was established. The compound (4) was synthesized from the commercially available methyl 2-aminothiophene-3-carboxylate and formimidamide...

4-(Thieno[3,2-d]pyrimidin-4-yl)morpholine derivatives is an important intermediate which inhibited tumor necrosis factor alpha and nitric oxide. In this work, a rapid and green synthetic method for compound (5) was established. The compound (5) was synthesized from the commercially available methyl 3-aminothiophene-2-carboxylate...

Afatinib (1) exhibited potential biological activities in medicine. There are shortcomings in the synthesis route of afatinib in the literature, the product yield is low and the post-processing is complicated. Therefore, in this paper, the two-step synthetic route of afatinib was optimized. The two-step...

3-phenyl-1H-pyrazole (1) is an important intermediate for the synthesis of many biologically active compounds.
