[reaction: see text] A novel Cu(I)-catalyzed asymmetric 1,3-dipolar cycloaddition of azomethine ylides with acrylates has been developed. Up to 98/2 exo/endo selectivity and up to 98% enantiomeric excess have been achieved.

toid, erythematous-vesicular, or urticarial lesions appear on the periphery of and at a distance from the area of the original contact. Histopathology findings are nonspecific. Spongiosis and exocytosis are common findings, although vacuolar degeneration of the basement membrane or epidermal necrolysis is more unusual. Acrylate-induced allergic contact dermatitis usually manifests as eczematous...

Nail art (creation and decoration of artificial nails) is a growing fashion trend. Proportionally to its popularity, the number of allergic reactions to the materials used has recently increased. We report the case of a nail art operator who developed occupational allergy to acrylates, manifested with the unusual simultaneous presence of asthma and dermatitis. Cutaneous lesions only affected ar...

The present study investigated two novel biophotopolymer classes that are chemically based on non-toxic poly (vinyl alcohol). These vinylesters and vinylcarbonates were compared to standard acrylates in vitro on MC3T3-E1 cells and in vivo in a small animal model. In vitro, both vinylester and vinylcarbonate monomers showed about tenfold less cytotoxicity when compared to acrylates (IC50: 2.922 ...

Dienes have been formed with good stereoselectivity and in good yield from simple aldehydes and acrylates/acrylonitrile in the presence of a phosphine and a Lewis acid through a modification of the Morita reaction.

Methylmethacrylate was first reported in 1941 as a cause of contact dermatitis. Since then, occupational contact allergies to acrylates in dentistry, orthopedic surgery, printing industry and industry have been reported, but few reports are found in the literature as a consequence of the contact with sculptured artificial acrylic nails which are increasingly popular. We describe here 3 patients...

[reaction: see text] Free radicals generated by the decarboxylation of dimethoxydioxanecarboxylic acids derived from L-(+)-tartaric acid and L-glyceric acid added to some maleimides and acrylates with high stereoselectivity. This method provides easy access to some chiral building blocks.

Ruthenium-catalyzed highly selective codimerization of N-acetyl α-arylenamines with ethyl acrylates is reported. This codimerization reaction provides a new efficient method for the synthesis of α,β-unsaturated γ-amino esters with a quaternary center.

An efficient iron(II)-catalyzed alkoxycarbonylation reaction between N-vinylacetamides and carbazates is reported. The corresponding useful highly substituted (β-acylamino)acrylates could be obtained in reasonable to good yields and stereoselectivity under mild reaction conditions.
