Cooperative reaction chemistry derived from a borata-diene framework.
The bifunctional frustrated BH(-)/B hydridoborate nucleophile/borane Lewis acid pair 6 is prepared starting from the borata-diene 3 by a sequence of sequential protonation/hydride attachment, followed by hydroboration with Piers' borane [HB(C6F5)2]. The trans-1,2-bifunctional system 6 reduced carbon monoxide eventually to the aldehyde product 10.
متن کاملAsymmetric aza-Diels-Alder reaction of Danishefsky's diene with imines in a chiral reaction medium
The asymmetric aza-Diels-Alder reaction of chiral imines with Danishefsky's diene in chiral ionic liquids provides the corresponding cycloadduct with moderate to high diastereoselectivity. The reaction has proved to perform better at room temperature in ionic liquids without either Lewis acid catalyst or organic solvent. Chiral ionic liquids are recycled while their efficiency is preserved.
متن کاملReaction chemistry ABC-style.
F or a time, membrane proteins proved intractable to X-ray crystallography. There were difficulties of overexpression and purification, multiple choices of solubilizing detergent that could only be decided by trial and error, unwillingness to crystallize, and often, poor diffraction from resultant crystals. However, the tide now seems to be turning, and in PNAS, Oldham and Chen (1) present an X...
متن کاملAntimicrobial Peptides Derived from Milk: A Review
Milk proteins provide a natural source of bioactive peptides with potential health benefits and applications in the food industry. The release of these peptides from milk proteins is achieved either by hydrolysis using digestive proteases or by lactic acid bacteria fermentation. Peptides, particularly those derived from milk proteins, can exert a wide range of nutritional, functional and biolog...
متن کاملComplex Chemical Reaction Networks from Heuristics-Aided Quantum Chemistry.
While structures and reactivities of many small molecules can be computed efficiently and accurately using quantum chemical methods, heuristic approaches remain essential for modeling complex structures and large-scale chemical systems. Here, we present a heuristics-aided quantum chemical methodology applicable to complex chemical reaction networks such as those arising in cell metabolism and p...
