The present invention discloses substituted 1,3-benzodioxoles which possess anti-diabetic and/or anti-hyperglycemic and/or anti-obesity properties in humans and other animals.

Substituted 5-(2-((2-aryl-2-hydroxyethyl)amino)propyl)-1,3-benzodioxoles

A process is disclosed for obtaining the R,R isomer of: ##STR1## wherein R.sub.1 and R.sub.2 may be one or more groups which may be the same or different and are selected from the group consisting of hydrogen, C.sub.1 to C.sub.4 alkyl, C.sub.1 to C.sub.4 alkoxy, hydroxy, halogen, trifluoromethyl, carboxy, hydroxyalkyl, alkoxycarbonyl, C.sub.1 to C.sub.4 thioalkyl, sulfonyl and sulfinyl; X is a divalent radical consisting of ##STR2## wherein R' is hydrogen; R.sub.2 and R.sub.3 may be the same or different and are selected from the group consisting of hydrogen and C.sub.1 to C.sub.4 alkyl; R.sub.5 and R.sub.6 are selected from the group consisting of hydrogen, carboxy, alkoxycarbonyl, hydroxymethyl, --CH.sub.2 OCH.sub.2 COOR.sub.7 and --CH.sub.2 OCH.sub.2 CH.sub.2 OR.sub.7 where R.sub.7 is hydrogen or C.sub.1 to .sub.4 alkyl; except that R.sub.5 and R.sub.6 may not both be hydrogen; and the asterisks denote asymmetric carbon atoms; said process comprising the steps of:
