According to a couple reports about Curt Herzstark, inventor of the Curta Calculator, who was allowed to continue working on the calculator while in Buchenwald, with the goal of giving one to Hitler for his Birthday, and the reward of becoming an honorary Aryan. He didn't make it. The camp was liberated before the deadline passed. But he did go on to make the calculator.

Not sure if that's what you were looking for, but it's kinda cool.

I'm not entirely sure what you mean by deportation (to the concentration/death camps in the east?), but maybe the following will fit your criterion.

The Jews of Operation Bernhard were imprisoned in the concentration camp Sachsenhausen and had one task: Counterfeiting foreign currency and other official papers. The 144 Jewish prisoners enjoyed a comparatively "good" life and 142 survived Nazi Germany.

Another case that might interest you is that of the family of the philosopher Ludwig Wittgenstein. While Ludwig and other family members had already emigrated to the UK and other safe havens two of his older sisters remained in Austria and had no intention of leaving when the Anschluss happened. Thanks to their industrious father and grandfather this family with Jewish roots, became quite rich and climbed to the highest echelon of Austrian society. By 1938 they were completely assimilated, the grandparents having been baptized, but all of the sudden considered Jewish and those that stayed in Austria were subject to the Nuremberg laws.

As the family had financial assets in Switzerland and the US the Nazis started to blackmail family members abroad. After some negotiations Paul Wittgenstein, one of the brothers of Ludwig, agreed to pay millions, including over 200 kilos of gold, in exchange for his sisters' safety. Their grandparents were officially and counter-factually declared of Aryan descent and those that stayed in Austria survived the war. The family was literally too valuable.

EDIT: What I completely forgot to mention is that there were official exemptions from deportation, if people were considered too important for the war effort. That was the method Oskar Schindler exploited to save the Jews he employed. I'm sure there were similar instances throughout WWII that saved individuals from being deported. Maybe someone else can give you other examples.
