R 2 is selected from OR 14 and NR 6 R 7 ;
R 6 and R 7 are each independently selected from H, alkyl, cycloalkyl, heterocycle or benzyl, wherein said alkyl, cycloalkyl, or benzyl is optionally substituted with one or more groups independently selected from —F, —OR 8 , —NR 12 SO 2 R 13 , —C(═O)NR 12 R 13 or R 6 and R 7 together with the nitrogen atom to which they are attached form a heterocyclic ring, further wherein said heterocyclic ring is optionally substituted with one or more —OH;
R 8 is selected from hydrogen and alkyl, and
R 12 , R 13 and R 14 are each independently selected from H and alkyl, wherein said alkyl is optionally substituted with —OH; and
n is 1 or 2.
2. A compound having the formula VIIa:
