R5 is selected from H, P(═O)(OH)2 and P(═O)(OH)—O—P(═O)(OH)2;
R6 is selected from H and alkyl;
R7 and R8 are independently selected from H, alkyl, halogen and hydroxymethyl
R9 and R19 together with the carbon atoms to which they are attached form a mono or bicyclic ring system selected from cycloalkyl, cycloalkenyl, heterocycloalkyl and heterocycloalkenyl;
R11 is selected from H and alkyl;
R12 is selected from H and alkyl;
m is 0, 1, 2 or 3;
n is 1, 2 or 3;
p is 0 or 1;
q is 0, 1, 2 or 3;
r is 0, 1, 2, 3, 4 or 5;
s is 0 or 1;
Base is a natural or non-natural nucleobase, and
wherein each alkyl, cycloalkyl, cycloalkenyl, heterocycloalkyl, heterocycloalkenyl, aryl and heteroaryl may be optionally substituted as described herein.
