Synthesis of the modified decadeoxynucleotides 16–20 having the sequence d(G1pC2pG)3pT4x1T5x2T6x3T7pG8pC9pG10) and containing one (x2 = CH2, x1 = x3 = p, i.e., 16), two (x1 = x3 = CH2, x2 = p, i.e., 17, x2 = x3 = CH2, x1 = p, i.e., 18 and x1 = x2 = CH2, x3 = p. i.e., 19) or three (x1 = x2 = x3 = CH2, i.e., 20) -O-CH2-O- linkages could be accomplished using the respective mono-, di- or tri(-O-CH2-O)
改性decadeoxynucleotides的合成16-20具有序列d(G 1 PC 2 PG)3的pT 4 X 1 Ť 5 X 2 Ť 6 X 3 Ť 7的pG 8 PC 9的pG 10)和含有一个(X2 = CH 2, X1 = X3 = p,即,16),两个(X1 = X3 = CH 2,X 2 = p,即,17,X2 = X3 = CH 2,X 1 = p,即,18并且x1 = x2 = CH 2,x3 = p。即,19)或三个(X1 = X2 = X3 = CH 2,即,20)-O-CH 2 -O-键可以使用相应的单- ,二-或三(-O-CH来完成2 -O )3'-O-亚磷酰胺6、10和14作为进入的合成子。16-20与它们的天然互补链的杂交提供了稳定的双链体,通过1D和2D - 1 H-NMR和UV超色性技术对其进行了研究。
