A depth image assisted method for color image background subtraction
Autor: Bo-sheng zhang, 張博勝
100
Background subtraction is an important process to extract foreground objects for real-time analysis, such as tracking and recognition. The major task in background subtraction is to generate a background model which is then subtracted from t

Template Synthesis to Solve the Unreachable Ortho C-H Func-tionalization Reaction of Iodobenzene
Autor: Bo-Sheng Zhang, Wan-Yuan Jia, Yi-Ming Wang, Svenja Warratz, Ze-Qiang Zhang, Xue-Ya Gou, Yong-Min Liang, Xi-Cun Wang, Zheng-Jun Quan, Lutz Ackermann
With the development of ortho C-H functionalization in Pd/NBE chemistry, the catalytic systems used are becoming increasingly complex. The increasingly complex catalytic systems may have created technical barri-ers for researchers in other fields to

Visible-Light-Driven Iodine-Catalyzed Synthesis of Unsymmetrical Disulfides via Oxidative Coupling
Autor: Xi-Cun Wang, Zheng-Jun Quan, Yan-Jun Fu, Ming-Zhe Ren, Bo-Sheng Zhang
Publikováno v: Synthesis.
Herein, a facile and environmentally friendly oxidative coupling reaction to obtain unsymmetrical disulfide compounds, without using metal or organic dyes as photocatalyst and only using a catalytic amount of iodine, was developed. Oxygen is used as

Visible light promoted polyhalomethylation of alkenes: alkylation and cyclization
Autor: Tong-Lin Wang, Bo-Sheng Zhang, Jing-Jiang Liu, Xiao-Jun Liu, Xi-Cun Wang, Zheng-Jun Quan
Publikováno v: Organic Chemistry Frontiers. 9:1004-1009
The report describes a visible light promoted carbochloromethylation of 2-bromomethyl acrylate and N-arylmethacrylamide, and a series of trihalomethyl substituted allylic acid esters and indolone derivatives were synthesized.

Palladium-Catalyzed Synthesis of Tricyclic Indoles via a N–S Bond Cleavage Strategy
Autor: Yuke Li, Zheng-Jun Quan, Xue-Ya Gou, Bo-Sheng Zhang, Fan Wang, Xicun Wang, Yong-Min Liang, Ying-Hui Yang, Wan-Yuan Jia
Publikováno v: Organic Letters. 23:7518-7523
In palladium/norbornene (Pd/NBE) chemistry, the "ortho effect" has been proven to be a key factor in the process of β-carbon elimination to extrude NBE. Herein, we found that the o-iodoaniline protected by a p-methoxybenzenesulfonyl group can recove

Ruthenium‐Catalyzed Stereo‐ and Site‐Selective ortho‐ and meta ‐C−H Glycosylation and Mechanistic Studies
Autor: Xue‐Ya Gou, Yuke Li, Wei‐Yu Shi, Yu‐Yong Luan, Ya‐Nan Ding, Yang An, Yan‐Chong Huang, Bo‐Sheng Zhang, Xue‐Yuan Liu, Yong‐Min Liang
Publikováno v: Angewandte Chemie International Edition. 61
C-aryl glycosides are popular basic skeletons in biochemistry and pharmaceutical chemistry. Herein, ruthenium-catalyzed highly stereo- and site-selective ortho- and meta-C
