Something else is wrong with the sentence, Antonija. The catalog was also synchronised? With what? It is also difficult to synchronise
synonymy (I presume we are talking about zoological taxonomy here), since
synonymy already means 'the same names'.
As for the literature, I don't think you need '
professional' at all; the phrase '
the literature' in this context automatically means ' the publications in the professional field being discussed'.
