Performance management algorithm of financial shared service center based on Internet of Things public cloud privacy protection.

The Internet of Things (IoT) refers to the use of various communication technologies to achieve the interconnection of everything in cyberspace, and to achieve smart home and intelligent transportation, thus generating unprecedented amounts of data. In the financial sharing center, all businesses can extract effective data from these massive databases for analysis, and use data analysis tools to collect business, financial, human, process, knowledge and social data. At present, various types of IT (Internet Technology) systems have been widely used in financial sharing centers.

Direct amidation of aldoses and decarboxylative amidation of alpha-keto acids: an efficient conjugation method for unprotected carbohydrate molecules.

With use of iodine as an appropriate oxidant, unprotected and unmodified aldoses undergo oxidative amidation with a variety of functionalized amines, alpha-amino esters, and peptides, whereas KDO, sialic acid, and other alpha-keto acids proceed with oxidative decarboxylation followed by in situ amidation. Glycoside bond and many other functional groups are inert under such mild reaction conditions. This reaction protocol for direct ligation of carbohydrate molecules looks promising in the development of a general and efficient synthesis of glycoconjugates.

Dichloromethane activation. Direct methylenation of ketones and aldehydes with CH2Cl2 promoted by Mg/TiCl4/THF.

[reaction: see text] This Mg-TiCl4-promoted CH2-transfer reaction of CH2Cl2 represents an extremely simple, practical, and efficient methylenation of a variety of ketones and aldehydes, especially in enolizable or sterically hindered ketones such as 2,2-dimethylcyclohexanone, camphor, and fenchone.
