The zwitterion 6 was obtained similarly by reaction of l-[(tri-ethoxysilyl)methyl]-l-methyl-morpholinium iodide with l,2-dihydroxy-4-nitrobenzene in boiling acetonitrile in the presence of KOH (Scheme 1). Compounds 4-6 were isolated in 75-85 % yield as crystalline solids their identity was established by elemental analyses, NMR experiments, and mass-spectrometric investigations.

The strategy was chosen to (1) link the amino acid derivative to a polystyrene-supported hydroxylamine, (2) carry out the cyclization under Mitsunobu conditions, and (3) assemble a short peptide on the free amino group present in the ring. This approach has been shown to be suitable particularly for solid-phase synthesis, as the supported (3-lactam could be easily separated from the by-products of the Mitsunobu reaction. The linker employed was a polystyrene resin carrying 0-trityl-hydroxylamine linker, prepared according to the literature procedure [151]. After the deprotection of Fmoc group carried out with 20% piperidine in DMF, the L-cbz-serine (or L-cbz-threonine) was coupled using (4,6-Dimethoxy-[l, 3, 5]-triazin-2-yl)-4-methyl-morpholinium chloride (DMTMM) [152] in M-methylpyrrolidone (NMP) in the presence of M,M-diisopropylethylamine (DIPEA) (Schemes 42 45).

The syntiiesis of DPP-4 inhibitor, Saxagliptin 1 (Figure 4.21) required key intermediate (5S)-5-aminocarbonyl-4,5-dihydro-lH-pyrrole-l-carboxylic acid,l-(l,l-dimethyl ethyl)-ester 76 [22-24]. Direct chemical ammonolysis resulted in unacceptable levels of amide racemization and side-product formation. Milder, two-step hydrolysis-condensation protocols using coupling agents such as 4-(4,6-dimetiioxy-l,3,5-triazin-2-yl)-4-methyl-morpholinium chloride (DMT-MM) were compromised by reduced overall yields [103].

Figure 21 shows temperature dependence of electrical conductivity and magnetic susceptibility of MEM(Af-methyl-iV-ethyl-morpholinium)-(TCNQ)2 [70]. At about 335 K it undergoes a metal-insulator transition accompanied by the onset of a two-fold superstructure and a temperature dependent magnetic susceptibility characteristic of localized moments. It is considered as depicted in Fig. 22(a) that a dimerized TCNQ accepts an electron localized by, for example, the Mott transition or the Wigner crystallization. The solid curve shown in Fig. 21(b) denotes the theoretical prediction for the magnetic susceptibility of a one-...
