Öğe Synthesis of alkyl nitrones by reaction of aldehyde and ketone oximes with alpha,beta-unstaturated esters in the presence of Lewis acid(MAIK NAUKA/INTERPERIODICA/SPRINGER, 2009) Kocak, A.; Malkondu, S.; Kurbanli, S.Reactions of pyridinecarbaldehyde oximes, methyl pyridyl ketone oximes, furfural oxime, cinnamaldehyde oxime, and crotonaldehyde oxime with acrylic and methacrylic acid esters in the presence of a Lewis acid catalyst at room temperature followed the conjugate addition pattern to give the corresponding alkyl nitrones in good yield. The best yields were obtained using a 1: 1 mixture of CdI(2) and BF(3) center dot Bu(2)O as catalyst.
