Design and Synthesis of Antifreeze Glycoproteins and Mimics

Antifreeze glycoproteins are an important class of biological antifreezes that have potential applications in many areas of medicine, agriculture and industry in which ice crystal growth is damaging.

Synthetic Studies towards New Nucleoside Analogues: Preparation of (±)‐1′,4′‐Dimethyladenosine

The latter reaction was thoroughly studied, as it is the key step of the sequence, and very particular reactivity of the 1?,4??dimethylated sugars was observed. Secondary reactions took place according to original mechanisms and delivered original byproducts.

Using Taguchi Robust Design Method to Develop an Optimized Synthesis Procedure for Nanocrystals of ZSM‐5 Zeolite

A Taguchi orthogonal experimental design with three levels of the above?mentioned parameters was used to optimize the experiment parameters by the analysis of variances (ANOVA). Applying the Taguchi method significantly reduced the time and cost for optimization.

Diversity Through a Branched Reaction Pathway: Generation of Multicyclic Scaffolds and Identification of Antimigratory Agents

A library of 91 heterocyclic compounds composed of 16 distinct scaffolds has been synthesized through a sequence of phosphine?catalyzed ring?forming reactions, Tebbe reactions, Diels?Alder reactions, and, in some cases, hydrolysis. This effort in diversity?

Synthesis of Biaryl Compounds Using Tandem Ruthenium‐Catalyzed Ring‐Closing Metathesis

Tandem ring?closing enyne metathesis (RCEM)/ring?closing olefin metathesis (RCM) of tetraenynes with Grubbs second?generation catalyst, followed by elimination, was found to be a new and efficient synthetic approach to biaryl compounds.

Efficient Preparation of the Key Intermediate in Corey's Tamiflu Synthesis

A very efficient two?step synthesis was developed to prepare the key intermediate in Corey's Tamiflu synthesis. DBU (1,8?diazabicyclo[5.4.0] undec?7?ene) was used as a multifunctional catalyst for a series of reactions in a one pot procedure.

Direct Synthesis of Water‐Tolerant Alkyl Indium Reagents and Their Application in Palladium‐Catalyzed Couplings with Aryl Halides

A direct result: Alkyl indium reagents are synthesized by the insertion of indium into alkyl halide mediated by CuCl. The synthetic utility of these reagents is demonstrated by their palladium?catalyzed coupling with aryl halides (see scheme).

Triptycene-Derived Calix[6]arenes: Synthesis, Structures, and Their Complexation with Fullerenes C60 and C70

Two pairs of novel triptycene-derived calix[6]arenes 4 a,b and 5 a,b have been efficiently synthesized through both one-pot and two-step fragment-coupling strategies starting from 2,7-bis(hydroxymethyl)-1,8-dimethoxytriptycene 1.
