[3 + 2]-Cycloadditions of Azomethine Imines and Ynolates
Winterton, Sarah E.,Ready, Joseph M.
, p. 2608 - 2611 (2016)
A novel [3 + 2]-cycloaddition between azomethine imines and lithium ynolates is described to synthesize bicyclic pyrazolidinones. These bicyclic pyrazolidinones are versatile intermediates to form β-amino acids and monocyclic pyrazolidinones. High diaster
