(12 pts) Each of the reactions below is drawn with two possible reaction conditions. If only one of the two reaction conditions would generate the given molecule as the major product, circle those conditions. If both sets of conditions would accomplish the reaction, circle BOTH . If neither set of reaction conditions would succeed, circle NEITHER . Circle one answer only. LiAlH4 and NaBH4 are both reducing agents, and add hydride ( H- ) to C=O bonds.

equivalent to a C=O containing functional group, and our amide needs two to make an amine. So regardless of whether LiAlH(OtBu)3 adds or not, it certainly won’t make ... 4 points for each protection/deprotection cycle. 1 point for using correct reagents in each protection/deprotection; 2 points for drawing correct molecules on the right.

Orthogonal protection schemes are usually milder because selective deprotection is governed by alternative cleavage mechanisms rather than by reaction rates. Since the pioneernig work of Bergmann and Zervas, the development of new protecting groups has been deeply tied to peptide chemistry. Protection
