An arrayed combination of water-soluble deep cavitands and cationic dyes has been shown to optically sense insect pheromones at micromolar concentration in water. Machine learning approaches were used to optimize the most effective array components, which

As easy as ABCD: (-)-Jiadifenin was synthesized in eighteen reaction steps from 1-[(E)-(4′-bromo-2′-butenyl)oxy]-4-methoxybenzene. Key features of this synthesis include: 1) Ireland-Claisen rearrangement to produce the two contiguous quaternary centers at
On the selectivity of oxynitrilases towards α-oxygenated aldehydes

Different α-alkoxy and α,β-di-alkoxy substituted aldehydes have been submitted to the catalytic action of the oxynitrilases from almond (PaHNL) or from Hevea brasiliensis (HbHNL), in order to explore the possibility of using these enzymes for the preparation of complex cyanohydrins. The selectivity of both enzymes towards these compounds was found to be largely dependent on the substitutents, being low with the aldehydes carrying the sterically more demanding phenyl substituent. Contrary to the chemical addition of HCN, which always occurs with a slight preference for the formation of the anti diastereoisomers, the enzymatic cyanuration - occurring with a facial preference, Si or Re according to the biocatalyst used - gave a mixture of cyanohydrins that, depending on the starting enantiomeric aldehyde, can be enriched in the syn diastereoisomers.
Stereoselective Synthesis of Alcohols, XII. Synthesis of the C-9/C-13 Partial Structure of Methynolide

Reduction of the β-ketoester 5 by yeast led to the β-hydroxyester 7, which was converted to the epoxyesters 13 and 15.Their transformation into the dioxolane carboxylic esters 14 and 16 by SnCl4/acetone proceeded under inversion at C-3.The structure 14 was secured by independent synthesis from D-ribonolactone.The enolate derived from 14 or 16 gave on methylation predominantly the cis-substituted product 21.The isomeric product 2 was obtained from D-fructose in six steps.
