(‐)‐3‐Kthylpiperidine and (R)‐(‐)‐2‐ethylglutarie acid have been chemically correlated through N‐subslituted α‐ethylglutarimides obtained from the oxidation of optically active N‐ethyl‐ and N‐benzyl‐3‐ethylpiperidine with ruthenium tetroxide. The (R)‐(‐) configuration of (‐)‐3‐ethylpiperidine was confirmed by CD measurements. The selective oxidation of endocyclic methylenes linked to the nitrogen atom was explained in term of different conformational freedom of endo‐ and exocyclic methylene groups.
Die N‐substituierten Phenylpiperidine (I) und Phenylpiperazine (II) werden auf bekannten Wegen hergestellt und ihre antibakteriellen und antimykotischen Eigenschaften untersucht.
3‐Ethyl‐pyridin (I) wird zu den stereoisomeren 3‐Ethyl‐piperidinen (II) reduziert, und diese werden mit Rutheniumtetroxid zu (IIIb) oxidiert bzw. in die Derivate (IIIa), (IIIc) und (IIId) übergeführt.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
