What is the appropriate sequence of reaction conditions used to synthesize valine from acetamidomalonic ester?

Question

Quizplus · Accepted Answer

The appropriate sequence of reaction conditions to synthesize valine from acetamidomalonic ester is:
(1) treatment with strong base such as NaOCH(CH3)2;
(2) reaction with CHBr(CH3)2 and (CH3)3CCO2H to form the protected valine derivative; and
(3) deprotection with HCl and heat to yield the desired valine product.
Option C is the only choice that follows this sequence.
