The complex of Na(+) with phenylalanine (Phe) is a prototype for the participation of cation-pi interactions in metal-ion binding to biological molecules. A recent comparison of this complex with the Na(+)/alanine (Na(+)/Ala) counterpart suggested on

This unit describes the preparation of alkylthioalkylated and formamidoalkylated alcohols, an amidoalkylated alcohol, a hydroxylalkylated phosphoramidate, and their phosphoramidothioate derivatives, all of which have been identified as heat-sensitive
The ribonucleoside building block, N2-isobutyryl-2′-O-propargyl-3′-O-levulinyl guanosine (Scheme 1), was prepared from commercial N2-isobutyryl-5′-O-(4,4′-dimethoxytrityl)-2′-O-propargyl guanosine in a yield of 91%. The propargylated guanyl
