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...

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. It was synthesized from acetophenone (2) and hydrazine through two steps including Knoevenagel condensation, Cyclization reaction reaction. In this paper, three novel 3-phenyl-1H-pyrazole derivatives...

With the great "internet +" concept putting forward and widely used, life in cities are getting much more convenient. The city market can witness the intelligentialize lifestyle everywhere, while for the country, as the blank market, it becomes the competition areas. In the base of the e-supply chain...

Cross border e-commerce not only broke through the barriers between countries, so that international trade to trade without borders, but it is also causing great changes in world economic and trade. Cross-border electronic business platform is divided into information services platform and online trading...

A single band E-Shaped Patch antenna with Defective Ground Structures (DGS) was proposed. The overall dimension of the antenna is (32*31.5*1.64) mm. This antenna produces bandwidth ranges from (2.3 to 2.5) GHz, which supports ISM band application. This provides reflection coefficient about -32dB respectively....

China Camellia fruit shell to mechanical machine has not been popular, especially in rural areas, this paper designs a kind of advanced and applicable Camellia fruit shell device, used to make more efficient fruit tea, Camellia fruit hulling machine, which comprises a shell, a cutting mechanism, tie...

In 2005, Sun, Hsieh, and Hwang proposed two secure e-mail protocols with perfect forward secrecy. In the first protocol, the authors apply smart card and Diffie-Hellman key agreement scheme to achieve the perfect forward secrecy. However, due to it requires a smart card to store some parameters, it is...

Web service is very important for both e-commerce and e-government. However, web service process based on syntax level can’t deal with some user query very effectively. In order to make user get more information on the internet, semantic web is presented and a lot of related research results have been...

Fuzzy distance is applied on data analysis, classification, and production positioning analysis widely. In this paper, We introduction a fuzzy distance by using graded mean integration representation of generalized fuzzy number and the span of fuzzy number, We also discuss the distance of the linguistic...

A general phenomenon puzzles all investors is that on one hand, most individual investors believe they need to construct the portfolio consisting of 15 or more stocks to prevent risk because that large investment companies frequently get high returns is due to they obey the existing investment theory...

We have experimentally demonstrated the gain-clamped wideband optical amplifier using a DCF-based Raman amplifier and an semiconductor optical amplifier for 90-nm wide bandwidth amplification with good gain flatness (of 3 dB) as well as dispersion compensation of 10Gb/s DWDM signals over 100-km SMF link....
