I think you're after entry.chemical_name and/or entry.synonyms, as in ConQuest the name of the entry is found in the compound field.
So, for example
>>> from ccdc import io
>>> csd_reader = io.EntryReader('CSD')
>>> entry_abebuf = csd_reader.entry('ABEBUF')
>>> print entry_abebuf.chemical_name
5H,11H-Dibenzo(b,f)(1,5)diazocine-6,12-dione pyridine clathrate
>>> print entry_abebuf.synonyms
As in this case entry ABEBUF only has one name - if there are multiple trivial/common names these will appear in the synonyms field.
I hope that's what you're after!
