Abstract:

The hexahydro-pyrrolizidine skeleton is a structural motif found in several biologically active compounds. The pyrrolizidinic alkaloids are a good example of compounds isolated from natural sources which exhibited this motif in their structures and remarkable biological effects. The biological relevance of these compounds justifies the development of new approach to them. We disclose herein a facile and fast approach to the synthesis of poly-hydroxylated pyrolizidinones and pyrrolizidines using Morita-Baylis-Hillman adducts as substrate.
