Novel bicyclo[2,2,1]heptanes and hept-2Z-enes are substituted at the 5-position by a 6-carboxyhex-2-enyl group or a modification thereof as defined herein, and at the 6-position by a group <CHEM> in which R1 represents an aliphatic hydrocarbon residue or an aliphatic hydrocarbon residue substituted directly or through an oxygen or sulphur atom by an aromatic residue, R2 represents hydrogen and R3 represents a hydroxy group, or R2 and R3 together represent the oxygen atom of a carboxyl group. These compounds are of value for use in the synthesis of certain biologically active 5,6-disubstituted bicyclo[2,2,1]heptanes and hept-2Z-enes. |
