Chemoselective and Site-Selective Reductions Catalyzed by a Supramolecular Host and a Pyridine-Borane Cofactor

Supramolecular catalysts emulate the mechanism of enzymes to achieve large rate accelerations and precise selectivity under mild and aqueous conditions. While significant strides have been made in the supramolecular host-promoted synthesis of small molecules, applications of this reactivity to chemoselective and site-selective modification of complex biomolecules remain virtually unexplored. We report here a supramolecular system where coencapsulation of pyridine-borane with a variety of molecules including enones, ketones, aldehydes, oximes, hydrazones, and imines effects efficient reductions under basic aqueous conditions. Upon subjecting unprotected lysine to the host-mediated reductive amination conditions, we observed excellent ?-selectivity, indicating that differential guest binding within the same molecule is possible without sacrificing reactivity. Inspired by the post-translational modification of complex biomolecules by enzymatic systems, we then applied this supramolecular reaction to the site-selective labeling of a single lysine residue in an 11-amino acid peptide chain and human insulin.

Synthesis of antimalarial trioxanes via continuous photo-oxidation with 1O2 in supercritical CO2

The oxidation of an allylic alcohol to its hydroperoxides represents a key step in the synthesis of a series of spirobicyclic, antimalarial trioxanes. Herein, we investigate the continuous photo-oxidation of an allylic alcohol with 1O2 in scCO2, as a 'green' alternative to conventional methods, and examine the remaining two steps in the synthesis of antimalarial trioxanes from readily available starting materials.

Process for dehydrating 2-methylpentane-2,4-diol

A process for dehydrating 2-methylpentanediol-2,4 to a mixture of 2-methyl-1,3-pentadiene and 4-methyl-1,3-pentadiene at elevated temperature in the presence of an acid catalyst using a polyglycol ether as a heat carrier, wherein a polyglycol ether containing from 80 to 100% by weight of a polyethylene glycol dimethyl ether of the formula CH3(OCH2CH2)nOCH3 where n=2-8 and from 0 to 20% by weight of a polyethylene glycol monomethyl ether of the formula CH3(OCH2CH2)nOH where n=2-8 based in each case on the total mass of polyglycol ether, is used.
