Graphical Abstract

Weit reichende sterische Wechselwirkungen zwischen den 1,5-Diol-Schutzgruppen wurden bei der Synthese des Chromophorgerüsts von C-1027 für die erfolgreiche atropselektive Makrolactonisierung (A im Schema) genutzt. Darauf folgende LiN(SiMe3)2/CeCl3-unterstützte Acetylidaddition an eine Aldehydeinheit im System des starren Makrocyclus (B) lieferte das neungliedrige Zielringsystem mit einer hochgespannten Diineinheit.
