redirect multiple urls

Hello there,

I need to redirect multiple pages to a single page.

For example from the old website I have:

https://www.domain.it/adrona/sistemi-di-alimentazione-dellacqua-di-rete-da-laboratorio/crystalex/
https://www.domain.it/adrona/sistemi-di-alimentazione-dellacqua-di-rete-da-laboratorio/crystal-7/
https://www.domain.it/adrona/sistemi-di-alimentazione-dellacqua-di-rete-da-laboratorio/crystal-10/
https://www.domain.it/adrona/sistemi-di-alimentazione-dellacqua-di-rete-da-laboratorio/onsite/
https://www.domain.it/adrona/sistemi-di-alimentazione-dellacqua-di-rete-da-laboratorio/q-front/
https://www.domain.it/adrona/sistemi-di-alimentazione-dellacqua-di-rete-da-laboratorio/d-front/
https://www.domain.it/adrona/sistemi-di-alimentazione-dellacqua-di-rete-da-laboratorio/d-front-plus/

And all of them will redirect to a single page

https://www.domain.it/adrona


Which is the correct expression? I've tried regex options and used something like:

old
^/adrona/(.*)

new
https://www.domain.it/adrona/$1

but it does not work.
May you help me with this issue?
Thanks

M
