  ABSTRACT: 16-Isopropyl-5, 9-dimethyltetracyclo [10.2.2.0(1, 10).0(4, 9)] hexadec-15-ene-5, 14-dicarboxylic acid (1b) was prepared from rosin through a Diels-Alder addition reaction. Then, a group of Schiff bases derived from 1b was synthesised. Their structures were characterised by IR,(1)H-NMR, MS and elemental analysis. The antibacterial activities of these newly synthesised Schiff bases were also investigated. The results show that these compounds possess antibacterial activities against Staphylococcus aureus and Escherichia coli. Among them, compounds 5a, 5b and 5c, exhibit remarkable antibacterial activity against E. coli.

  ABSTRACT: The title compound, C(24)H(40)O(3)·C(2)H(6)O, is a substituted tetra-cyclo-[10.2.2.0(1,10).0(4,9)]hexa-decane derivative obtained from the reduction of maleopimaric acid which was isolated from a maleic anhydride modified rosin. In the crystal, the triol mol-ecule and the ethanol solvent mol-ecule are linked by hydroxyl O-H⋯O hydrogen bonds, giving a two-dimensional network structure.

  ABSTRACT: The title compound, C(23)H(38)O(2), a tetra-cyclo-[10.2.2.0(1,10).0(4,9)] hexa-decane structure, crystallized with four independent mol-ecules in the asymmetric unit. In the crystal, these independent mol-ecules are linked by O-H⋯O hydrogen bonds, forming a polymeric chain propagating in [100].
