- W2088646988 abstract "Durch Claisen-Umlagerung der Acrylsäureester 7 und 21 wird die Konfiguration der Cyclohexenole trans-2 und trans-17 auf die Aldehyde 11 und 23 übertragen. Robinson-Anellierung führt von dort zu den Titelverbindungen 15a und 27a. Die Aufbaufolge ist über 14a, b iterativ angelegt. Zwei Ester des all-trans-Tercyclohexylalkohols 27a mit breiten smektischen Phasenbereichen werden beschrieben. Aliphatic Liquid Crystals, 8. — Bi-and Tercyclohexyl Derivatives by Claisen Rearrangement Claisen rearrangement of the acrylic esters 7 and 21 transfers the configuration of the cyclohexenols trans-2 and trans-17 to the aldehydes 11 and 23. Robinson annelation converts the latter to the title compounds 15a and 27a. The synthetic sequence is designed to be iterative via 14a, b. Two esters of the all-trans-tercyclohexyl alcohol 27a with broad smectic phase ranges are described." @default.
