The general scheme for utilizing a polymer substrate for synthetic purposes is shown in Fig. 9-2. A substrate S is covalently bonded to an appropriate polymer support to yield the polymer substrate  (which is usually of the insoluble type). The polymer substrate P S

is treated with a low-molecular-weight reagent (and/or catalyst) R to yield the polymerP S bound product  0 and spent reagent R0 . Filtration separates the polymer-bound product. An appropriate reaction is carried out to cleave the desired product S0 from the polymer. The spent polymer support is ltered off, leaving the crude product S0 in the ltrate. The puri ed product S0 is obtained from the ltrate after solvent evaporation and appropriate puri cation.

One of the most important applications of the polymer substrate technique is the solid-phase synthesis of polypeptides developed by Merri eld [Barany et al., 1988; Erickson and Merri eld, 1976; Kates and Abericio, 2000; Kent, 1988; Merri eld, 1978; 1985, 1988; Seward and Jakubke, 2002; Stewart, 1980]. Merri eld received the 1984 Nobel Prize in Chemistry for this achievement. Polypeptide synthesis is of interest for two reasons: (1) it is useful in con rming the structure of naturally occurring biological macromolecules and (2) it is a source of these substances as well as analogs that may show more desirable biological activity. Polypeptide synthesis involves the formation of an amide linkage between the amino and carboxyl groups of successive a-amino acid monomers. In reacting two different amino acids with each other, it is necessary to protect the amino group of one amino acid and protect the carboxyl of the other amino acid. This prevents self-reaction of each amino acid with itself and directs the synthesis in the desired cross-reaction route. There are two copolymerization routes and only one of these is the desired route. For example, alanylglycine (Eq. 9-72) and glycylalanine (Eq. 9-73) are possible from the cross-reaction of alanine and glycine. Synthesis of alanylglycine requires that the amine end of alanine and the carboxyl end of glycine be protected prior to reaction. Synthesis of glycylalanine requires that the amine and carboxyl ends of glycine and alanine, respectively, be protected.

The solid-phase synthesis of a polypeptide is described in Fig. 9-3. Chloromethylated polystyrene (usually based on 1% DVB) is commonly used as the polymer support. Reactions are carried out in nonaqueous media, usually methylene chloride, although DMF has also been used. The rst amino acid monomer (often referred to as a unit or residue) is attached to the polymer support by nucleophilic displacement of the benzylic chloride by carboxylate anion. Reasonable reaction rates are achieved by having high concentrations of the carboxylate anion present by using either the cesium or trialkyl ammonium salt instead of the carboxylic acid. The attachment of the rst amino acid to the polymer support also serves the purpose of protecting the carboxyl group. The amino group of the amino acid must be protected (often referred to as N-blocking or N-protecting) to prevent self-condensation of that monomer during attachment to the support. A variety of protecting groups were studied, including carbobenzoxy, p-toluene sulfonyl, triphenylmethyl, and t-butoxycarbonyl. The

t-butoxycarbonyl group (referred to as Boc) is usually formed by reacting the amino acid with 2-(t-butoxycarbonyloxyimino)-2-phenylacetonitrile. Di-t-butyl dicarbonate and t-butoxycarbonyl azide have also been used for synthesizing Boc-protected amino acids. The Boc

group is the most frequently used N-protecting group since it can be hydrolyzed, usually with 25 50% tri uoroacetic acid (TFA) in methylene chloride, without affecting the polymer support polypeptide bond (i.e., the benzyl ester bond formed in the rst step in Fig. 9-3).
