evolve, with participation of unreacted protoanemonin in the reaction conditions, to polycyclic compounds, through 1,6-addition, alkylation and intramolecular Michael addition processes. Constitution of the compounds obtained have been assigned on the basis of spectral characteristics and mechanistic approaches. The behaviour of in front of nucleophiles has been rationalized and generalized by means
