Abstract
A dinucleotide analogue of formula ##STR1## where B.sup.1 and B.sup.2 are each independently a monovalent nucleoside base radical; PA1 R.sup.1 is R.sup.1.sub.a or Z; PA1 R.sup.1.sub.a, R.sup.2, R.sup.3 and R.sup.4 are each independently hydrogen, halogen or hydroxy; PA1 R.sup.5 is R.sup.5.sub.a or Z; PA1 R.sup.6 is hydrogen or R.sup.6.sub.a ; PA1 R.sup.7 is hydrogen, alkyl-N,N-dialkylphosphoramidyl or R.sup.7.sub.a, R.sup.8 is R.sup.8.sub.a or Z, or the indicated R.sup.7 O and R.sup.8 together denote an isopropylidenedioxy group; PA1 R.sup.5.sub.a and R.sup.8.sub.a are each independently hydrogen, halogen, hydroxy, --OR.sup.10, --OCOR.sup.10 or silyloxy substituted by three C.sub.1 -C.sub.5 hydrocarbyl groups; PA1 R.sup.6.sub.a and R.sup.7.sub.a are each independently a C.sub.1 -C.sub.10 aliphatic radical, a C.sub.6 -C.sub.15 aromatic radical, a C.sub.7 -C.sub.30 araliphatic radical, --COR.sup.11, --SO.sub.2 R.sup.11 or silyl substituted by three C.sub.1 -C.sub.15 hydrocarbyl groups; PA1 R.sup.9 is hydrogen, a C.sub.1 -C.sub.8 aliphatic radical, a C.sub.3 -C.sub.8 cycloaliphatic radical, a C.sub.6 -C.sub.15 aromatic radical, a C.sub.7 -C.sub.13 araliphatic radical, an alkali metal …
