description The synthesis of structurally complex and highly strained natural products provides unique challenges and unexpected opportunities for the development of new reactions and strategies. Herein, the synthesis of (+)‐[5]‐ladderanoic acid is reported. En route to the target, unusual and unexpected strain release driven transformations were uncovered. This occurrence required a drastic revision of the synthetic design that ultimately led to the development of a novel stepwise cyclobutane assembly by an allylboration/Zweifel olefination sequence. (Ent)spannend: Die Synthese hoch gepannter Naturstoffe bietet exzellente Möglichkeiten für die Entwicklung neuer Reaktionen und Strategien. Bei der Synthese von (+)‐[5]‐Ladderansäure wurden ungewöhnliche, durch die Freisetzung sterischer Spannung bedingte Transformationen aufgedeckt, was eine drastische Überarbeitung des Syntheseplans erforderte, die schließlich zur Entwicklung einer neuartigen schrittweisen Cyclobutanbildung durch eine Sequenz aus Allylborierung und Zweifel‐Olefinierung führte.
