Imprinting of macromolecule such as proteins with molecular imprinting technique remains challenge because of their bulkiness, structural complexity and sensitivity of denaturation. The purpose of this study was to synthesize a Lys-MIP film on the surface of the MWNTs by surface molecular imprinting technique, and subsequently selectively recognized and purified Lys from egg white. The Lys-MIP film was prepare Read More

Conjugated polyelectrolytes (CPEs) have attracted much attention as an emerging sensory material because of their meritorious signal amplification, convenient optical detection, readily tunable properties, and easy fabrication. This review paper summarizes the advances in synthesis of conjugated polyelectrolytes (such as polyfluorene, poly(para-phenylene ethynylene), poly(para-phenylene), poly(para-pheny Read More

Molecular iodine has acquired an important role in organic synthesis due to its unique and powerful feature to catalyze organic transformations on account of its mild Lewis acidic character. The current review enlightens the versatile nature of the catalyst for numerous organic strategies including the synthesis of various heterocyclic compounds, iodination, protection- deprotection of functional groups etc.

The specific rates of solvolysis of chloromethyl phenyl sulfide [(phenylthio)methyl chloride] and its p-chloro-derivative have been determined at 0.0 oC in a wide range of hydroxylic solvents, including several containing a fluroalcohol. Treatment in terms of a two-term Grunwald-Winstein equation, incorporating terms based on solvent ionizing power (YCl) and solvent nucleophilicity (NT) suggest a mechanism similar to that Read More

Cembrane-type diterpenoids are a large and structurally varied group of natural products isolated from both terrestrial and marine organisms. The present paper reviews all the metabolites of cembrane diterpenes, reported up to 2010. The natural products discussed in this review can be divided into several different structural families featuring a variety of ring sizes and oxidation patterns. The currently known biological ac Read More

A new and efficient methodology for the Clauson-Kaas synthesis of N-aryl pyrroles, employing CeCl3.7H2O as catalyst, was developed. The transformation was performed in acetonitrile under reflux, using conventional heating and microwave irradiation. Employing NH4SCN/Oxiall as a new thiocyanating system for the so obtained N-aryl pyrroles, the synthesis 1-aryl-2-thiocyanato-1Hpyrroles was also successfully acco Read More

Methodology of a selection and environmental economy in nitration reaction of aromatics will be rather attractive to replace traditional sulfonitric acid process in industry. The cross-linked pillared clays originated from a natural bentonite show an obviously selective catalysis in nitration reaction of alkylbenzenes by respectively using nitric acid and a nitrogen dioxide/molecular oxygen system when compared with Kyodai-nitration.
