<D-> only works in MacVim.
A quick google will return a bunch of hacks and third party solutions. All the solutions I know either work system-wide or are application-specific: if you remap
Cmd in iTerm2 only, how are you going to open a new window or a new tab? With… with… the… MOUSE?
I can't imagine a good reason to remap the

Vim is not TextMate or whatever other editor you have used before. There is no way to transfer all your old habits seamlessly, point blank.
Instead of wasting your time trying to make Vim and your terminal into something that it's not and can't be you should learn how to use and customize Vim wisely. All your
Alt combos won't lead you anywhere. Especially in a terminal where
Alt is often problematic and
- it's portable on every platform
- it's less prone to conflicts with your OS or terminal emulator
- it opens a lot of easy to remember possibilities
