Simple and efficient synthesis of substituted 2-pyrrolidinones, 2-pyrrolones and pyrrolidines from enaminones of Baylis-Hillman derivatives of 3-isoxazolecarbaldehydes

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.

Alternate, Easy and practical synthesis of allyl amines from acetyl derivatives of Baylis-Hillman adducts using Methanolic Ammonia

A methanolic ammonia-mediated alternate, easy and practical stereoselective synthesis of allyl amines from the acetyl derivatives of Baylis-Hillman adducts is described.
