I think this will work for you, the search pattern has the optional www and redirects using the back reference C:2, the rule has a condition to only run against non https.

This is the pattern:

"^(www\.)?(.*)$"

where:

{C:0} - www.domain.de
{C:1} - www.
{C:2} - domain.de

Here's the rule in full:

  <rewrite>
    <rules>
      <rule name="SecureRedirect" stopProcessing="true">
        <match url="^(.*)$" />
        <conditions>
          <add input="{HTTPS}" pattern="off" />
          <add input="{HTTP_HOST}" pattern="^(www\.)?(.*)$" />
        </conditions>
        <action type="Redirect" url="https://{C:2}" redirectType="Permanent" />
      </rule>
    </rules>
  </rewrite>
