Abstract

The debenzylation of 2,6,8,12-tetraacetyl-4,10-dibenzyl-2,4,6,8,10,12-hexaazatetra-cyclo[5.5.0.03,11.05,9]dodecane by catalytic hydrogenolysis in a mixture of HCOOH with other RCOOH (R = Me, Et, Pri) is accompanied by the N-formylation of the liberated secondary amino groups. The alkaline hydrolysis of the obtained products makes it possible to remove the formyl groups with the retention of the acetyl groups. [ABSTRACT FROM AUTHOR]

15. Synthesis and stereoisomerism of N-oxides of the decahydroquinoline series

Author

Akhrem, A. A., Ukhova, L. I., and Sakovich, N. F.

Abstract

Summary 1.A study was made of the oxidation of 4-ethynyldecahydro-L,2-dimethyl-4-quinolinol and two isomeric 4-ethyldecahydro-1,2-dimethyl-4-quinolinols with hydrogen peroxide and with peroxyacetic acid.2.With the aid of thin-layer chromatography on alumina and the crystallization of picrates it was shown that in the oxidation of each of these amino alcohols two isomeric (cis and trans) N-oxides are formed.3.It was found for the first time that in the thin-layer chromatography of the picrates of the isomeric N-oxides on alumina the picrates break down into their components. Because of this it is possible to use the individual picrates of the isomeric N-oxides as reference compounds for N-oxides in the chromatography of mixtures of the latter. This method can probably be extended to other types of molecular compounds.
