Two molecules of the title compound are related by a twofold non-crystallographic symmetry operation. There is an extensive hydrogen-bonding network, as well as van der Waals interactions between alkyl groups.
## Abstract Ausgehend von (R)‐(−)‐3‐Hydorxybuttersäure‐ethylester (**6**) wurde die Titelverbindung **5** über 11 Stufen in einer Gesamtausbeute von 9.5% synthetisiert. Die Kettenverlängerung um vier C‐Atome wird dabei durch Wittig‐Reaktionen (**10** → **11**, __13__ → __14__), die Methylverzweigun
