Examples 1 to 5 in Table 1.1 illustrate simple displacement of a bromide (reactions 1 and 4) or a chloride (reactions 2,3, and 5). Reaction 1 illustrates a radical chain extension reaction that reacts ethylene and methyl bromoacetate 1.17), with AIBN (flzofeis-isobutyronitrile) as a catalyst, to produce the requisite bromo-cster. The reaction is not very selective, however, since it produced a mixture of 1.18 and 1.19. The reaction was not very selective and the observed products arose from addition of one and two equivalents of ethylene, respectively, to 1.17. Subsequent treatment with ammonia, the key reaction for this section, led to a mixture of 4-aminobutanoic acid and 6-aminohexanoic acid, 1.2 and 1.4. In reaction 2, ethyl 4,4,4-trifluoropropanoate (J.20) reacted with PCI3 and bromine to give ethyl 3-bromo-4,4,4-trifluorobutanoate, which reacted with ammonia to give 3-amino-4,4,4-trifluorobutanamide, 1.21. Reaction 3 shows the reaction of P-halo lactic acid (3-chloro-2-hydroxypropanoic acid, 1.22) with 28% aqueous ammonia, in an autoclave, to give isoserine (3-amino-2-hydroxypropanoic acid, 1.23). Both halo-acids l and halo-esters 2 have been converted into hydroxy amino acids typical products are 3-... [Pg.5]

A closely related chiral template is L-P-malamidic acid 5.182), which was converted to 5.183 using a hypervalent iodine species. Acid hydrolysis gave S-isoserine (3-amino-2-hydroxypropanoic acid, 5.35). [Pg.172]
