Synthesis of 4-Chloro-N, N-Dimethyl Pyridine Car Box Amide

Yongli Duan, Zhimin Li, Qidong Tang, Rui Li, Shan Xu
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...

Synthesis of N-(3-chloro-4-fluorophenyl)-6-nitro-7-((tetrahydrofuran-3-yl) oxy) quinazolin-4-amine

Caolin Wang, Yiqiang Ouyang, Zhou Lan
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...

Apriori Data Mining on Rotationally Invariant Multiresolutional Moments for Pattern Recognition

Annupan Rodtook, Stanislav Makhanov
We propose a new feature selection procedure based on a combination of a pruning algorithm, Apriori mining techniques and fuzzy C-mean clustering. The feature selection algorithm is designed to mine on a multiresolution filter bank composed of rotationally invariant moments. The numerical experiments,...
