Optically active benzene derivatives and process for preparation thereof

Abstract

Disclosed are novel optically active benzene derivatives represented by the formula (I): ##STR1## wherein R represents an alkyl or alkoxyalkyl group having 1 to 20 carbon atoms, which group may contain a halogen; Z represents a hydrogen atom or a halogen atom; l and n each represents a number of 0 or 1; and * indicates asymmetric carbon atom, and a process for preparing the above optically active benzene derivative which comprises debenzylating an optically active benzyl derivative represented by the formula (II): ##STR2## wherein, R, Z, l, n and * have the same meanings as defined above, and A represents a hydrogen atom, a lower alkyl group, a lower alkoxyl group or a halogen atom.

Dependencies are inferred from the claim text.
