1,6-Dioxo-cyclodeca-3,8-diene (4) and the cis and trans forms of 1,6-diamino-cyclodeca-3,8-diene (7) have been synthesized from naphthalene via isotetralin (1). No transannular reaction was observed during the reduction of the dioxime of (4) to the diamine (7).

qualitative study has been carried out on selected polycyclitols to evaluate the potential of conformationallocking of hydroxy groups in lending predictability to the O–H···O hydrogen-bonding network observed in the crystalstructures of such compounds. The polycyclitols employed in this study are conformationallylocked with all the hydroxy groups destined to be axial owing to the trans ring fusion(s) in
