    摘要: The present invention provides new imino compounds having the formula I ##STR1## wherein R.sub.1 represents an aliphatic or cycloaliphatic hydrocarbon radical, unsubstituted or substituted phenyl, or phenyl-lower alkyl or diphenyl-lower alkyl, which radicals are unsubstituted or substituted in the phenyl ring(s),R.sub.2 represents unsubstituted or substituted phenyl, unsubstituted or substituted monocyclic heteroaryl or lower alkyl,R.sub.3 represents hydrogen, lower alkyl, a carbonyl group linked with R.sub.2 to form a five-membered ring, or the group R.sub.6 --CO wherein R.sub.6 represents lower alkyl or unsubstituted or substituted phenyl,R.sub.4 represents, if present, hydrogen or lower alkyl which is independent or is linked with R.sub.1 to form a five- to seven-membered ring which can contain as ring members two aromatic ring carbon atoms of an unsubstituted or substituted phenyl or phenyl-lower-alkyl radical R.sub.1, and as a six- or seven-membered ring also epoxy or lower alkylimino which is separated by two, or at least two, carbon atoms from the nitrogen atom given in the formula I,R.sub.5 represents, if present, hydrogen or lower alkyl,A represents a straight- or branched-chain lower alkylene having 2 to (5-n.sub.1 -n.sub.2) chain members,Z represents epoxy, epithio, imino or lower alkylimino, andm.sub.1 and m.sub.2 represent 0 or 1 and together always represent 1,n.sub.1 represents 1 or, if Z represents imino or lower alkylimino and n.sub.2 represents 1, can also represent 0,n.sub.2 represents 0 or 1,and wherein two additional bonds, either corresponding to the dashed lines or corresponding to the dotted lines, are present, with m.sub.1 representing 0 in the former case and m.sub.2 representing 0 in the latter case, and the acid addition salts, in particular the pharmaceutically acceptable acid addition salts thereof. These new substances possess valuable pharmacological properties, particularly hypoglycaemic activity, and can be used as oral antidiabetics. Specific embodiments are 2-[2-(cyclohexylimino)-2-phenyl-ethylidene]-pyrrolidine and 2-[2-(cis-2-cyclohexyl-cyclopentylimino)-2-phenylethylidene]-pyrrolidine, and their pharmaceutically acceptable acid addition salts.
