METHOD FOR PRODUCING N-SUBSTITUTED 3beta-AMINONORTROPANES

摘要

The invention relates to a method for producing, on the basis of the corresponding 3-oxonortropane or the corresponding 3alpha-aminonortropane, N-substituted 3beta-aminonortropanes of formula (I), wherein R<1> is defined as in the claim. According to the inventive method, the starting compounds are converted to the corresponding imines by means of an arylmethylamine or an arylaldehyde, said imines are tautomerized or isomerized and then hydrolyzed. The invention also relates to the novel compounds of formula (V), wherein R<1> and Ar are defined as in the claims.
