You are trying to alias the *instance* method #new which doesn't exist. 
#new is a *class* method so you need to alias it in the metaclass. 
Something like:

class KK
end

class << KK
  alias_method :oldnew, :new
  def new
    yield if block_given?
    oldnew
  end
end

(You need the class to exist first before you access the metaclass.)
