A Deprotonation Approach to the Unprecedented Amino-Trimethylenemethane Chemistry: Regio-, Diastereo-, and Enantioselective Synthesis of Complex Amino Cycles

The first realization of the amino-trimethylenemethane chemistry is reported using a deprotonation strategy to simplify the synthesis of the amino-trimethylenemethane donor in two steps from commercial and inexpensive materials. A broad scope of cycloaddition acceptors (seven different classes) participated in the chemistry, chemo-, regio-, diastereo-, and enantioselectively generating various types of highly valuable complex amino cycles. Multiple derivatization reactions that further elaborated the initial amino cycles were performed without isolation of the crude product. Ultimately, we applied the amino-trimethylenemethane chemistry to synthesize a potential pharmaceutical in 8 linear steps and 7.5 % overall yield, which previously was achieved in 18 linear steps and 0.6 % overall yield.

Chapter 3: Key Roles of Cavity Portals in Host-Guest Binding Interactions by Cucurbituril Hosts

This chapter summarizes research work showing that electrostatic interactions may have considerable effects on the stability of complexes formed by the cucurbit[n]uril hosts. Focusing primarily on work carried out by the author’s research group with the cucurbit[7]uril (CB[7]) molecular receptor, this review highlights the role played by electrostatic interactions involving the host cavity portals, in which considerable negative charge density accumulates due to the carbonyl oxygens lacing the portal rims. Electrostatics are responsible for diminished binding affinities between CB[7] and a number of anionic guests containing one or more carboxylate groups. These electrostatic interactions can be used effectively to control the average location of CB[7] along axle-type guests having terminal -COOH groups as a function of their state of protonation, leading to switchable pseudorotaxane systems. They can also be utilized to advantage to develop favorable lateral interactions between CB[7] and other molecular receptors, which results in systems showing cooperative self-assembly.

Continuous assembly of supramolecular polyamine-phosphate networks on surfaces: Preparation and permeability properties of nanofilms

Supramolecular self-assembly of molecular building blocks represents a powerful “nanoarchitectonic” tool to create new functional materials with molecular-level feature control. Here, we propose a simple method to create tunable phosphate/polyamine-based films on surfaces by successive assembly of poly(allylamine hydrochloride) (PAH)/phosphate anions (Pi) supramolecular networks. The growth of the films showed a great linearity and regularity with the number of steps. The coating thickness can be easily modulated by the bulk concentration of PAH and the deposition cycles. The PAH/Pi networks showed chemical stability between pH 4 and 10. The transport properties of the surface assemblies formed from different deposition cycles were evaluated electrochemically by using different redox probes in aqueous solution. The results revealed that either highly permeable films or efficient anion transport selectivity can be created by simply varying the concentration of PAH. This experimental evidence indicates that this new strategy of supramolecular self-assembly can be useful for the rational construction of single polyelectrolyte nanoarchitectures with multiple functionalities.

The use of Al(OTf)3 as a new efficient catalyst for the direct nucleophilic substitution of the hydroxy group of ferrocenyl alcohols is described. This catalyst, originally developed for the mono-substitution of ethylene glycol nucleophiles of different length has shown a high activity with other carbon-, nitrogen-, and sulfur-based nucleophiles. In all the studied cases, no more than 1 mol % of catalyst was needed to allow fast and clean reactions.

Cyanoferrocenes as redox-active metalloligands for coordination-driven self-assembly

Ferrocene-based Lewis bases have found utility as metalloligands in a wide variety of applications. The coordination chemistry of cyanoferrocenes however, is underexplored. Herein, we describe a new synthetic protocol for the generation of cyanoferrocenes. The coordination chemistry of these metalloligands to [Cu(NCMe)4][PF6], [(PPh3)2Cu(NCMe)2][PF6] and [(dppf)Cu(NCMe)2][PF6] salts has been explored, providing crystallographic evidence of cluster and polymeric forms of 1,1?- and 1,2-dicyanoferrocene complexes. The stability of the complexes and ligand dissociation were found to be strongly solvent-dependent.

Biphenyl-lithium-TEGDME solution as anolyte for high energy density non-aqueous redox flow lithium battery

Non-aqueous redox flow batteries, because of larger operating voltage, have attracted considerable attention for high-density energy storage applications. However, the study of the anolyte is rather limited compared with the catholyte due to the labile properties of redox mediators at low potentials. Here, we report a new strategy that exploits high concentration organic lithium metal solution as a robust and energetic anolyte. The solution formed by dissolving metallic lithium with biphenyl (BP) in tetraethylene glycol dimethyl ether (TEGDME) presents a redox potential of 0.39 V versus Li/Li+, and a concentration up to 2 M. When coupled with a redox-targeted LiFePO4 catholyte system, the constructed redox flow lithium battery full cell delivers a cell voltage of 3.0 V and presents reasonably good cycling performance.

Colorimetric Aptasensor Based on Truncated Aptamer and Trivalent DNAzyme for Vibrio parahemolyticus Determination

In this work, after optimizing the original aptamer sequence by truncation and site-directed mutagenesis, a simple and sensitive colorimetric aptasensor was established for detecting the widespread food-borne pathogen Vibrio parahemolyticus (V. parahemolyticus). The detection strategy was based on the competition for an V. parahemolyticus specific aptamer between its complementary DNA (cDNA) and V. parahemolyticus. The aptamer-conjugated magnetic nanoparticles (MNPs) were used as capture probes, and the G-quadruplex (G4) DNAzyme was employed as the signal amplifying element. Under optimal conditions, a wide linear detection range (from 102 to 107 cfu/mL) was available, and the detection limit could be as low as 10 cfu/mL. This method was also used to detect V. parahemolyticus in contaminated salmon samples, and the results showed good consistency with those obtained from standard plate counting method. Therefore, this novel aptasensor could be a good candidate for sensitive and selective detection of V. parahemolyticus without complicated operations.
