2,3,6,7-Tetrasubstituted Perhydroanthracenes: Stereoselective Synthesis and Biconformationality Studies

Abstract: 2,3,6,7‐Tetrasubstituted perhydroanthracenes with the relative configuration 2β,3α,4aα,6β,7α,8aβ,9aα,10aβ have been synthesized stereoselectively. The biconformationality of these compounds has been investigated in solution by NMR and in the solid state by X‐ray crystallography. A triple‐ring flip 2 → 3 was realized for the first time by the covalently induced transition 29 → 30.

“…In these structures, a substituent plays a role of 'conformational lever', and the cyclohexane moiety is a mechanical transmitter. These ideas were successfully explored also by Costero et al [26][27][28][29][30], and were expanded by Koert et al [31][32][33][34][35][36] to decaline and perhydroanthracene derivatives. These ideas were successfully explored also by Costero et al [26][27][28][29][30], and were expanded by Koert et al [31][32][33][34][35][36] to decaline and perhydroanthracene derivatives.…”

“…Die konformative Transmission verläuft über einen Tripel-Ringflip. [9] Molekulare Signaltransduktion durch konformative Transmission führt nach Stimulation durch ein Signal zu einer Konformationsänderung auf der Rezeptorseite (Abbildung 1 a). Diese Bewegung wird durch den Transducer auf die Effektorseite übertragen, wo eine weitere Konformationsänderung zu einem lesbaren Effekt führt.…”

“…[10±13] Die beiden all-Sessel-Konformere des bikonformativen [14,15] cis-anti-cis-Perhydroanthracens sind durch einen Tripel-Ringflip [8] ineinander überführbar. Ein tetrasubstituiertes [9] cis-anti-cis-Perhydroanthracen vom Typ 1 mit zwei Rezeptorsubstituenten (rot) und zwei Effektorsubstituenten (blau) wurde als Transducer gewählt (Abbildung 1 b). Im Konformer 2 stehen die Rezeptorsubstituenten axial und die Effektorsubstituenten äquatorial.…”
