SNAr Mechanism of Piperidine with 2,4-dinitrobenzene & Meisenheimer complex Synthesis

a)Write a detailed mechanism for the reaction of piperidine with 2,4-dinitrochlorbenzene. b) A "spiro" species has two rings that have one carbon atom in common. Outline a synthesis of the spiro Meisenheimer complex shown, starting with 1-chloro-2,4,6-trinitrobenzene. (attached file)

tBoc Problem

I'm completely stuck with this problem. I know the tBoc group can be used as a protecting group, but I don't know how to use that to seperate enantiomers. Problem: Describe in 5 sentences or less, how would you seperate enantiomers of Phenylalanine-ethylester using (S)-tBoc-alanine.
