title: Construction of the [6-7-5-5] tetracyclic core of all the carbocyclic frameworks of yuzurimine-type alkaloids.
abstract: Yuzurimine-type alkaloids make up a sub-family of Daphniphyllum alkaloids structurally featuring a [6-7-5-5] tetracarbocyclic core framework. In this manuscript, we describe our construction of the [6-7-5-5] tetracarbocyclic core of yuzurimine-type alkaloids by using a unique in situ intramolecular Wittig reaction and Sm-mediated cyclization as key steps.
