As a starting point:

(cl-loop for p in package-alist
         for name = (car p)
         unless
         (cl-loop for pkg in package-alist thereis
                  (memq name
                        (mapcar 'car
                                (package-desc-reqs (cadr pkg)))))
         collect name)
