Abstract
Asymmetric inverse electron-demand 1,3-dipolar cycloaddition of ynolates with chiral nitrones produced 5-isoxazolidinones with good diastereoselectivity. These products were easily converted into optically pure β-amino acids and chiral γ-butyrolactones.
Key words
asymmetric synthesis - cycloadditions - diastereoselectivity - nitrones - ynolates
