Über Verbindungen mit Urotropin‐Struktur, LIII. Ringschlußreaktionen ausgehend von cis,cis ‐1,3,5‐Tris‐(alkylamino)cyclohexanen

Abstract: Ausgehcnd von ris,cis-l,3,S-Triaminocyclohexan (1) werden neue, ergiebige Methoden zur Darstellung von cis,cis-l,3,5-~ris(benzylaniino)-(4a), cis,cis-1,3,5-Tris(methylamino)cyclohexan (4c) und cis,cis-l,3,5-Triaminocyclohexan-1V,N""-triessigsaure (4b) bcschricben. Durch Kondensation von 4a bzw. c mit Orthnameiscrr~aure-triathylcster sind 2,4,1O-Tribeiuyl-(5a) und 2,4,1O-Trimethyl-2,4,IO-tria~aadamantun (5b) zuginglich. Durch Reaktion von 4c mit Phosphoroxychlorid oder Phosphortrichlorid wird ein einracher Zuga… Show more

“…Analogues of compounds 1-5 could not be prepared from L when its imine bonds had been reduced to alkylamine with NaBH 4 (L was reduced in methanol with NaBH 4 using the method in ref. 23). This may imply that the cavity plays a role in stabilising discrete species such as 1-5.…”

“…[33] In explorative experiments, however, the C=N double bonds in 15a proved resistant to their hydrogenative saturation and bridging interconnections. [34] With this 86th report on "Photochemical Transformations", a series comes to an end which began in 1962, [35] in the earlier days of preparative, particularly mechanistic organic photochemistry. [36] Over the years, the use of light for the construction of molecules with unusual architecture, with unusual photophysical and chemical properties, has remained a major area of research performed in the group of the senior correspondence author (H. P.).…”
