Toomey and colleagues report the results of a survey of 14 early career researchers (ECRs) about "open science". On a whole, these ECRs view open science positively, but hold reservations about the impact adopting open science practices might have on their...
The article reports the catalytic isomerization of the branched cyanoolefin 2-methyl-3-butenenitrile (2M3BN) to the linear isomer 3-pentenenitrile (3PN) using nickel-phosphine complexes.
The authors report that the optimal catalytic experiment was carried...
Wanting to avoid a chromatographic separation of the Me esters as well as the greater expense of dimethyl itaconate, the reaction of alpha methyl benzylamine and itaconic acid was performed in xylene. The reaction was performed by adding the amine at 110 to...
Victor E. Marquez et. al. first introduced the concept of locked conformations, 2'-exo (North) and 3'-exo (South), of ribose ring in nucleosides. In this article the synthetic methodology and successful synthesis of receamic and conformationally locked South...

1) Reaction of Standard Condition
Using photo-induced (hn 254), copper- catalyzed (10% CuI), two ratio base(LiOt-Bu), CH3CN/DMF as solvents and
stirring for 24 hrs at room temperature, Amides react with inactivated...
Ureas are very widely used synthetic targets in pharmaceutical industry especially as kinase inhibitors. Using this methodology we have synthesized thousands of unsymmetrical ureas as kinase inhibitors. This method is a very mild, high yielding and can work...
A detailed route for the synthesis of the "S" enantiomer of 4-TIPS-3-butyn-2-ol in 90% enantiomeric purity by reduction of the ynone precursor by the Noyori catalytic system was reported by Marshall et al. The ease of catalyst preparation, operational...
In one of my Ph.D. projects where I was working on the total syntheses of glycosphingolipids, I followed this reference to prepare some of the intermediates. This is a very important publication in the glycolipid field since it is among the few papers that...
Synthesized 2,6-Bis(3-dodecylthiophen-2-yl)benzobisthiazole following the procedure.
(1) The reaction was reproduced with higher yields (>25%).
(2) Added the 2-carboxylaldehydethiophene derviative by portions, used longer reaction time (24hs) and...
Summary:
This paper describes the conceptual density functional studies on (3+1) complexes of both Re(V) as well as Tc(V). The tridentate ligands have been varied in order to study the effect of the various combinations of N, O and S chelating sites on...
Summary:
This paper reports the synthesis of 2-arylbenzothiazoles via cyclocondensation of 2-aminothiophenol with various aldehydes. Polyethylene glycol-400 (PEG-400) has been used as both solvent and catalyst for the process. The procedure applied, is...
Summary:
The article presents the synthesis and characterization of two mononuclear Re(V) complexes. DFT and TD-DFT methods were employed for exploring the electronic structure and absorption spectra. Furthermore, the complexes were also tested for...
I followed this paper based on a need to synthesize their reported 7a as a substrate for a synthesis. I thought this method would be better than the previous Zinc-mediated cross-coupling approach. We found that the published procedure worked very well...
This paper was very helpful in my thesis research. I had some difficulties reproducing the cyclic voltammetry results in the beginning, which I later attributed to the surface of my electrode. Once I changed my polishing technique, I was able to reproduce...
The concept of citation network analysis is not new, but it is important. In this manuscript, Dr. Leng uses Web of Science to analyze a subfield of papers about radomized controlled trials (RCTs) of coronay heart disease between 1965-1984. While this topic...
