R2 is hydrogen or acyl. R3 is C3-6 alkyl. R4 is hydrogen; alkyl; -CH2R10 where R10 is optionally substituted phenyl or heteroaryl; or -CH(R12)O-R11 where R11 is hydrogen; alkyl; or -CH2Ph where Ph is optionally substituted phenyl; and R12 is hydrogen or alkyl. R5 is hydrogen; alkyl; or -CH(R13)COR14 where R13 is hydrogen or alkyl; and R14 is hydroxy, alkoxy or -NR6R7.
