title: Simple and efficient synthesis of substituted 2-pyrrolidinones, 2-pyrrolones, and pyrrolidines from enaminones of Baylis-Hillman derivatives of 3-isoxazolecarbaldehydes.
abstract: The enaminones, generated from derivatives of appropriately substituted Baylis-Hillman adducts of 3-isoxazolecarbaldehydes, undergo intramolecular ring-closure reactions to afford substituted 2-pyrrolidinones, 1,5-dihydro-2-pyrrolones, and N-substituted pyrrolidines in good yields.
