Investigation of Lewis Acid-Catalyzed Asymmetric Aza-Diels-Alder Reactions of 2H-Azirines

, p. 9958 - 9963 (2007/10/03)
Asymmetric Diels-Alder reactions with 2H-azirines as dienophiles have been studied. Diastereoselective reactions with an enantiopure azirine 1b, bearing a chiral auxiliary, gave substituted bi- and tricyclic tetrahydropyridines in high yield and stereoselectivity, under the influence of a Lewis acid. The novel enantioselective [4+2] cycloaddition reaction of 3-benzyl-2H-azirine carboxylate with cyclopentadiene was investigated with various chiral Lewis acid complexes and provided the corresponding tetrahydropyridines in moderate to low yield and enantioselectivity.

Asymmetric silyl nitronate cycloadditions with N-acryloyl (2R)-bornane-10,2-sultam, N-acryloyl (2S)-bornane-10,2-sultam, and N-methacryloyl (2R)-bornane-10,2-sultam have been studied. The asymmetric silyl nitronate cycloaddition/elimination methodology pr
On the Scope of Asymmetric Nitrile Oxide Cycloadditions with Oppolzer's Chiral Sultam. Total Syntheses of (+)-Hepialone, (-)-(1R,3R,5S)-1,3-Dimethyl-2,9-dioxabicyclooctane

, p. 4585 - 4595 (2007/10/02)
Cycloadditions of nitrile oxides with acryloyl derivatives of Oppolzer's chiral sultam produce stereoisomeric Δ2-isoxazolines in ratios of about 90/10 at 25 deg C.The major diastereomers can be isolated in pure form in 70-88percent yield.Synthe
