Abstract

Here, we report benzofuro[2,3-c]isoquinolines (FiQ) as novel blue AIEgens, in which a -OMe group substituent plays a crucial role in modulating intermolecular interactions, inducing a marked increase in emission of up to 150- and 460-fold in the aggregate and solid states, respectively. Our single-crystal X-ray diffraction analysis revealed that the edge-to-face interactions among phenyl groups generate tight networks that rigidify the assembled structures, resulting in AIE.

Abstract

Cordyceps Sinensis, known as winter worm and summer grass. This review summarized the overview of C. sinensis; chemical constituents and its biological studies. Further the bibliometric analysis performed which will help to broaden the knowledge and understanding of its research, topics, and growing trends. The search term “Cordyceps sinensis” was typed in google scholar and the appeared articles (total 1,134 articles) are selected, having citations more than 100 are 40 articles. Further evaluated according to the journal, year of publication, manuscript type, and first author. To make it more comprehensive the articles having more than 10 citations in the year 2017-18, at least 1 citation in 2019, and all articles of the year 2020 were also presented separately. The average number of citations among the top 40 manuscripts was 189, ranging from the highest 636 to lowest is 102 citations. The maximum number of articles in the top 40 were published in the Biological and Pharmaceutical Bulletin (n=5) and Life sciences (n=5), followed by the Phytomedicine (n=3). The highest cited paper is by Zhu JS, “the scientific rediscovery of an ancient Chinese herbal medicine: Cordyceps sinensis Part I”, published in 1998 with total citation 636. The most prevalent theme in the title is a polysaccharide (n=13) followed by antioxidant (n =4). Most of the research is performed by Chinese researchers. This bibliometric analysis identified the most influential articles in the field of C. sinensis research and discussed the overview on it

Abstract

This review aims to provide overall aspects of the history, biology, chemistry and the total synthesis of Aflavinines. The origin of this molecule traced back from the isolation and structural elucidation by Clardy and co-workers in 1980 [Tetrahed. Lett. 1980;21:243-246]. Most of the previously published total syntheses were covered in a brief summary and the key points of each work are highlighted. Moreover, various antiinsectant and antiviral Aflavinines congener are presented. This review is almost the first in Aflavinine topics covering all aspects in brief, to the best of our knowledge.

Abstract

The chemistry of salt is of great importance due to its immense potential from the daily life use to the synthetic chemistry like as workup material, as reagents, as phase transfer catalyst, as acid, as base, as catalyst, as agents for asymmetric synthesis, for some specific reaction transformation, to increase yield, decrease reaction time, ecofriendly synthesis, handling easiness and many more. This review summarizes the overall basic background of salts like how it is formed, nature of salt, generalized application of salts in daily life to synthetic chemistry, its application on other diverse fields, and list of individual categories of major commercially available salts with some structure. Besides having a lot of information on the internet about salts, this review tries to focus on a generalized overview that could be helpful for all to understand salt chemistry.
