Abstract: Abstract (β-diazo-α,α-difluoroethyl)phosphonates as an analog of difluoro diazoethane has been designed as a powerful tool for the assembly of α,α-difluorinated phosphonate-containing molecules. Here, we report a [3+2] dipolar cycloaddition reaction of in situ generated (β-diazo-α,α-difluoroethyl)phosphonates… read more here.

Abstract: A copper-catalyzed silylamination of α,β-unsaturated esters with silylboranes and hydroxylamines has been developed to afford the corresponding β-silyl-α-amino acid derivatives, which are of great interest in medicinal and pharmaceutical chemistry. Additionally, by using a suitable… read more here.

Abstract: The direct C2-addition of 5H-oxazol-4-ones to γ-keto-α,β-unsaturated esters catalyzed by a chiral squaramide has been achieved. Diverse highly functionalized γ-keto esters bearing a C2-oxazolone at the α-position were afforded in high yields with excellent stereoselectivities… read more here.

DOI: 10.1055/s-0036-1589162
Abstract: α,β-Unsaturated imides and α,β-unsaturated esters were found to undergo alcoholysis in the presence of trimethylphosphine. The reaction is initiated by nucleophilic addition of trimethylphosphine to the double bond of the α,β-unsaturated carbonyl compound. Saturated imides… read more here.

DOI: 10.3390/life12121999
Abstract: α-unsaturated esters are fruity-aromatic compounds which are largely spread in the volatilome of many different fruits, but they are rarely found in the volatilome of yeasts. The yeast S. suaveolens has been recently shown to… read more here.
