How, using, for example, rsync, to synchronize two directories, but pulling out ONLY files from the first one?

Question

linux

How, using, for example, rsync, to synchronize two directories, but pulling out ONLY files from the first one? That is, it was:

Каталог 1:
    -файл1
    -файл2
    -Каталог 1-1:
        -файл1-1
        -файл1-2

Became in the new directory:

Каталог2:
    -файл1
    -файл2
    -файл1-1
    -файл1-2

Roughly speaking, transfer files without creating internal directories. Thank you.
