In unix shells, you use shell patterns, which differ from Perl regular
expressions. Specifically:
* Matches any string, including the null string.
? Matches any single character.

That isn't even a Perl regular expression!
Depending on your shell, you can do that almost like you wrote.
E.g. in bash, it'd be:
mv *.{dump,asc,dat,txt,clean} tablecreation
