1. A compound having structure I:

  • ##STR3## wherein;

    X is H, a phosphate group, an activated phosphate group, an activated phosphite group, or a solid support;

    Y is H or a hydroxyl protecting group;

    Z is L1a, L1b -G1, L2, L2 -G2, NR3 R4, a nitrogen-containing heterocycle, a phosphate group, a polyether group, a polyethylene glycol group;

    L1a is alkyl having 1 to about 20 carbon atoms, alkenyl having 2 to about 20 carbon atoms, or alkynyl having 2 to about 20 carbon atoms;

    L1b is alkylene having 1 to about 20 carbon atoms, alkenylene having 2 to about 20 carbon atoms, or alkynylene having 2 to about 20 carbon atoms;

    L2 is aryl having 6 to about 14 carbon atoms or aralkyl having 7 to about 15 carbon atoms;

    G1 is halogen, OR1, SR2, NR3 R4, C(═

    NH)NR3 R4, NHC(═

    NH)NR3 R4, CH═

    O, C(═

    O)OR5, CH(NR3 R4)(C(═

    O)OR5), C(═

    O)NR3 R4, a metal coordination group, or a phosphate group;

    G2 is halogen, OH, SH, SCH3, or NR3 R4 ;

    R1 is H, alkyl having 1 to about 6 carbon atoms, or a hydroxyl protecting group;

    R2 is H, alkyl having 1 to about 6 carbon atoms, or a thiol protecting group;

    R3 and R4 are, independently, H, alkyl having 1 to about 6 carbon atoms, or an amine protecting group;

    R5 is H, alkyl having 1 to about 6 carbon atoms, or an acid protecting group;

    Q is L1b, G3, L1b -G3 or G3 -L1b -G3 ;

    G3 is C(═

    O), C(═

    S), C(O)--O, C(O)--NH, C(S)--O, C(S)--NH or S(O)2 ;

    n is 0 or 1;

    wherein if X is H, n is 1, and Q is SO2, then Z is not aryl;

    wherein if n is 0 and Z is L1a, then X is not H; and

    wherein if n is 1 and Q is L1b, then Z is not L1a.
