Controlling the structural deformation of organic molecules can drive unique reactions that cannot be induced only by thermal, optical or electrochemical procedures. However, in conventional organic synthesis, including mechanochemical procedures, it is difficult to control skeletal rearrangement in polycyclic aromatic hydrocarbons (PAHs). Here, we demonstrate a reaction scheme for the skeletal...

This paper introduces new dilated LMI conditions for continuous-time linear systems which not only characterize stability and H2 performance specifications, but also, H∞ performance specifications. These new conditions offer, in addition to new analysis tools, synthesis procedures that have the advantages of keeping the controller parameters independent of the Lyapunov matrix and offering suppl...

This note compares the substrate specificity of D-lactate dehydrogenase (D-LDH, EC 1.1.1.28) to that of L-lactate dehydrogenase (L-LDH, EC 1.1.1.27), illustrates three procedures that use D-LDH in synthesis and two methods for recycling NADH, and provides experimental details illustrating the use of D-LDH in organic synthesis.

To access P1-farnesyl-P2-indicator diphosphates, more efficient methods for the synthesis of farnesyl-phosphate and diphosphates were developed. The procedures reported here provide more flexible conditions than the conventional imidazolide and morpholidate coupling methods. Milder conditions for the synthesis of sensitive allylic diphosphates and greatly improved reaction efficiencies provide ...

There are several methods for the synthesis and analysis of hybrid systems that require efficient algorithms and tool for satisfiability checking. In this paper we give examples of such synthesis and analysis methods, and discuss decision procedures that can be used for this purpose.

Practical procedures for production of variously blocked compounds from L-rhamnose have been developed. These compounds are highly useful as indirect β-L-rhamnosyl donors. This approach represents a new method for the synthesis of aromatic nucleoside analogues and the synthesis of (3S, 4S, 5S, 6R) 3, 4, 5-triacetoxy-2-methyl-7,9-diaza-1-oxa-spiro [4,5]decane-10-one-8-thione (7).

An expeditious one-pot, ligand-free, Pd(OAc)2-catalyzed, three-component reaction for the synthesis of 2,3-diarylimidazo[1,2-a]pyridines was developed under microwave irradiation. With the high availability of commercial reagents and great efficiency in expanding molecule diversity, this methodology is superior to the existing procedures for the synthesis of 2,3-diarylimidazo[1,2-a]pyridines an...

Recent advances in pyridine synthesis are described. Modification of traditional condensation strategies continues to be a recurrent theme in contemporary literature. Advancements in transition-metal-catalyzed cyclization and cross-coupling procedures offer new routes to functionalized pyridine derivatives. These recently developed methodologies are a valuable addition to azaheterocycle synthesis.

A simple procedure is described for synthesis of oligonucleotides by phosphate chemistry. Chains can be constructed rapidly with minimal equipment (a syringe and reagent bottles). The method is illustrated by synthesis of d-TGCAGGTT. Pertinent supporting data on the effect of variations in the detritylation, condensation, oxidation, capping and cleavage steps in the synthetic approach and in is...
