Abstract

A total synthesis strategy was developed for the synthesis of luotonin A, B and their analogues using synergistic FeCl3/KI‐catalyzed oxidative cyclization. This protocol utilizes cheap and widely available N‐propargyl 2‐methyl‐quinazolinones and arylamines under mild conditions, and it has a wide substrate scope and high atom economy. Different natural products (luotonin A, B and derivatives) can be synthesized via a unique switchable approach. Further transformations from luotonin B to luotonin E and structural modification of natural products demonstrate the potential applications of this method. Moreover, camptothecin can also be modified with the reported protocol to afford the hydroxyl‐substituted product. [ABSTRACT FROM AUTHOR]

Abstract

The Shanghai Stock Exchange requires listed companies to submit and release the periodic financial reporting simultaneously based on extensible Business Reporting since 2009. Using financial companies and manufacturing companies as samples, this paper compares the disclosure quality of financial reporting on the internet. The result shows that financial reporting on the internet in the financial industry stays higher level than manufacturing industry. The results of this paper also support that research and application of extensible Business Reporting in China is still at lower stage, which needs further study. And there are still many difficulties in its application.

19. Iodine-catalyzed oxidative annulation: facile synthesis of pyrazolooxepinopyrazolones via methyl azaarene sp 3 C-H functionalization.

Author

Abstract

An iodine-catalyzed methyl azaarene sp 3 C-H functionalization has been developed for the synthesis of a seven-membered O -heterocyclic architecture containing three different heterocyclic aromatic hydrocarbons. This method can be applied to a wide range of substituted methyl azaarenes and diverse 2,4-dihydro-3 H -pyrazol-3-ones, and brings about the efficient preparation of 2,9-dihydrooxepino[2,3- c :6,5- c ']dipyrazol-3(7 H )-ones in high yields with the merits of low catalyst loading, good functional group tolerance and metal-free conditions.
