In the Internet I found

"For example with xmms2:
pacman -Qi xmms2 | sed -n '/^Optional/,$p' | sed '/^Required/q' | head -n -1 | cut -c19- | cut -d: -f1
- https://unix.stackexchange.com/questions/53080/list-optional-dependencies-with-pacman-on-arch-linux

so I reedited it to

for i in $(pacman -Q | cut -d\  -f1); do echo "##### "$i; pacman -Qi $(pacman -Q $i| cut -d\  -f1) | sed -n '/Deps/,$p' | sed '/^Required/q' | grep -v Required\ By | grep -v None | grep -v installed] ; done

To install all packages

"sudo pacman -S --asdeps $(pactree -l wine)" -

might do the job.
