A represents a single bond, CHR5-Y, CR5=CR6, CR5R7-CHR6 or CHR5, where R5 represents a hydrogen atom, hydroxyl group, halogen atom or alkyl group, R6 and R7 each represent a hydrogen atom, hydroxyl group, alkyl group, halogen atom or substituted sulfonyloxy group,
Y represents O, S or NH, and
W represents a substituted or unsubstituted benzene ring,
and processes for preparing the same.
