Elevated Plasma Von Willebrand Factor and Propeptide Levels in Malawian Children with Malaria

In children with malaria plasma VWF and propeptide levels are markedly elevated in both cerebral and mild paediatric malaria, with levels matching disease severity, and these normalize upon recovery. High levels of both markers also occur in retinopathy-negative 'cerebral malaria' cases, many of whom are thought to be suffering from diseases other than malaria, indicating that further studies of these markers will be required to determine their sensitivity and specificity

Studies towards the synthesis of FCRR toxin: an expeditious entry into 7-5-6 ring systems via [5+2] oxidopyrylium-alkene cycloaddition

Synthetic studies towards the diterpene natural product FCRR toxin have been undertaken. Ail intermolecular [5+2] oxidopyrylium-alkene cycloaddition reaction was employed to construct the 7-5-6 tricyclic framework. The reaction proceeded with very high regio- and stereoselectivity and the bridging ether was reductively cleaved to unmask the carbocycle. (C) 200

A furan route to the asymmetric synthesis of trans-fused polyether building blocks

A novel route towards chiral trans-fused polyether lactones 7 and 12 has been developed starting with commercially available furfural. Sharpless kinetic resolution and ring-closing metathesis reactions served as key steps in the strategy. (C) 200

Enantiospecific synthesis of [7R,6S,5S,4R]-triacetoxy-(-)-goniotriol

A short and efficient synthesis of [7R,6S,5S,4R]-triacetoxy-(-)-goniotriol starting form D-glucose is described. A sequence of ring closing metathesis (RCM) followed by a PCC oxidation was used to construct the core six-membered alpha,beta-unsaturated lactone moiety. (C) 2002 .

RCM/PCC oxidation strategy for synthesis of functionalized cyclic alpha,beta-unsaturated lactones: synthesis of (+)-triacetoxygoniotriol and its diastereomers

A novel methodology leading to the synthesis of (+)-triacetoxygoniotriol 2 from D-glucose is described. Construction of the core six-membered alpha, beta-unsaturated lactone moiety involved ring closing metathesis (RCM) followed by a PCC oxidation. Later exploiting the pseudo-symmetry of D-glucose three other diastereomers of triacetoxygoniotriol were synthesized using the developed methodology. (c) 200

[5+3] Cycloaddition of 3-Oxidopyrylium: A Novel Route to Functionalized Cyclooctanoids from Furans

We report a facile and efficient synthesis of highly functionalized cyclooctanoid derivatives by employing a dimerization reaction of 3-oxidopyrylium ylides. Different substituents are introduced on the dimer and the stereochemical outcome of the resultant cyclooctanoids is unambiguously established by single-crystal Xray analysis

Novel route to functionalized cyclooctanoids via [5+3] cycloaddition

The self-dimerization of 3-oxidopyrylium leading to stereocontrolled formation of highly functionalized cyclo-octanoids is described. Different functionalities were introduced on the dimer (3) and the stereochemical outcome was determined by single-crystal X-ray analysis. It is noteworthy that the hydrogenation of 3 in ethanol solvent gave the transannulated product 5, whereas the expected dihydro product 4 was obtained when the reaction was run in nonnucleophilic solvents. The mechanistic pathway is discussed

Scalable production of water-dispersible reduced graphene oxide and its integration in a field effect transistor

The development of environmentally benign, low-processing and low-cost approaches to the large-scale preparation of advanced nanomaterials based on the use of biological materials is currently attracting great interest. Here, we report the discovery that aqueous honey solutions reduce graphene oxide in a low-cost and an eco-friendly manner, yielding highly water dispersive functionalized reduced graphene sheets. The roles of honey in the reduction of graphene oxide of as-prepared graphene are demonstrated. The possible mechanism for the de-epoxidation of graphene oxide is elucidated. The fabricated a honey-reduced graphene oxide-based field-effect transistor exhibited ambipolar transfer characteristics, thereby demonstrating that the developed material may therefore have applications in electronic devices and sensors. © 2018 The Korean Society of Industrial and Engineering Chemistry.1
