- Abstract: Stereospecific polycyclic core formation of hapalindoles and fischerindoles is controlled by Stig cyclases through a three‐step cascade involving Cope rearrangement, 6‐ exo ‐trig cyclization, and a final electrophilic aromatic substitution. Reported here is a comprehensive study of all currently annotated Stig cyclases, revealing that these proteins can assemble into heteromeric complexes, induced by Ca 2+, to cooperatively control the stereochemistry of hapalindole natural products. Abstract : Die stereospezifische Bildung des polycyclischen Kerns der Hapalindole und Fischerindole wird durch Stig‐Cyclasen gesteuert, die eine dreistufige Kaskade aus Cope‐Umlagerung, 6‐ exo ‐trig‐Cyclisierung und elektrophiler aromatischer Substitution vermitteln. Die Proteine können sich induziert durch Ca 2+ zu heterotrimeren Komplexen zusammenlagern, um auf kooperative Weise die Stereochemie zu steuern.
