Phosphine-Catalyzed Annulations of Azomethine Imines: Allene-Dependent [3 + 2], [3 + 3], [4 + 3], and [3 + 2 + 3] Pathways
Risong Na,Chengfeng Jing,Qihai Xu,Hui Jiang,Xi Wu,Jiayan Shi,Jiangchun Zhong,Min Wang,Diego Benitez,Ekaterina Tkatchouk,William A. Goddard,Hongchao Guo,Ohyun Kwon +12 more
TL;DR: The salient features of this protocol--the facile access to a diverse range of nitrogen-containing heterocycles and the simple preparation of azomethine imine substrates--suggest that it might find extensive applications in heterocycle synthesis.

N-heterocyclic carbene-catalyzed [3+4] cycloaddition and kinetic resolution of azomethine imines
TL;DR: The first N-heterocyclic carbene (NHC)-catalyzed [3+4] cycloaddition of azomethine imines and enals is disclosed, in which the substrate chiral center that is remote from the NHC catalyst can be well resolved.
Journal ArticleDOI
Conversion of some 2(3H)-furanones bearing a pyrazolyl group into other heterocyclic systems with a study of their antiviral activity.
TL;DR: Evaluation of antiviral activity of selected examples of the compounds obtained was performed using two viruses: HAV and HSV-1, and some of the tested compounds showed promising activities.

Book
Comprehensive Heterocyclic Chemistry II
TL;DR: In this article, the CHEC III is organized in 15 volumes and closely follows the organization used in the previous edition: Volumes 1 and 2: Cover respectively three and four-membered heterocycles, together with all fused systems containing a three- or four-measured heterocyclic ring.

The chemistry of heterocyclic compounds
TL;DR: In this article, it was shown that one of the most common types of known quantities of phenyl phenyl is phenyl oxide (POP) oxide, which is a phenyl-oxyoxy phenyl (PE)-oxyoxyphenyl) that can be obtained from phenyl compounds.

1,3-Dipolar Cycloaddition Chemistry
TL;DR: The theory of 1-3-Dipolar Cycloadditions is discussed in this article. But it does not consider higher-order cycloaddings and higher order cycloreversions.
