Edit: I misunderstood the comment, but I will leave it as an example for removing certain elements in general.
If you want to remove the elements based on the value in the array, you have to loop over the array:

var $list = $("#myList"),
    toRemove = $();

for(var i = selectedItems.length; i--;) {
   toRemove = toRemove.add($list.find('option[value="' + selectedItems[i] + '"]'));
}
toRemove.remove();
