ABSTRACT:
The present invention provides aminocyclopentane derivatives which are saccharide analogs having extremely high .alpha.-glucosidase inhibitory effects and novel structures and expected to be usable or applicable to drugs or agricultural chemicals. An aminocyclopentane derivative represented by the formula (1), wherein R.sub.1 represents H while R.sub.2 represents CH.sub.2 OH, or R.sub.1 represents CH.sub.2 OH while R.sub.2 represents H and R.sub.3 represents a substituted or unsubstituted aryl group or an alkyl, alkenyl, alkynyl or hydroxyalkyl group having 1 to 10 carbon atoms, intermediates for the synthesis of the same, a process for producing the intermediates and a process for producing the aminocyclopentane derivative. ##STR1##
