%X We present here the first results from an ongoing spectroscopic survey of candidate compact groups selected in second Digitized Palomar Observatory Sky Survey, DPOSS II. The survey has been carried out at La Silla Observatory and 120 groups out of 261 possible candidates visible from the southern emisphere have been observed. A preliminary analysis of the results show that ¡­60% of the candidate are confirmed groups, and that the median redshift of the sample is z ¡­ 0.12. Other physical parameters of the confirmed groups, like crossing time, mass and median group radius, are very similar to those measured for the Hickson's compact groups sample in the local universe, suggesting that our new catalogue will be a valuable tool to extend at higher redshifts the investigation of such extreme objects.
