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.

Amino Acid-Protecting Groups

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

without affecting these functional groups (entries 3–6). Unfortunately, in the case of entries 7 and 8, the aromatic benzyl ethers gave poor yields in deprotection under our reaction condition. The p-methoxybenzyl (PMB) group is one of the most useful groups for alcohol protection, and there are various methods for selectively removing the PMB
