Studies toward total synthesis of (±)-caldaphnidine C via one-pot sequential intramolecular Vilsmeier–Haack and azomethine ylide 1,3-dipolar cycloaddition
An application of a one-pot sequential Vilsmeier–Haack cyclization and intramolecular azomethine ylide 1,3-dipolar cycloaddition toward the total synthesis of (±)-caldaphnidine C is presented. It allowed an efficient ...
A Versatile cascade of intramolecular vilsmeier-haack and azomethine ylide 1,3-dipolar cycloaddition toward tricyclic cores of alkaloids
Abstract: In the pursuit of synthetic efficiency, we developed an innovative one-pot transformation of linear substrates into bi- and tricyclic adducts using a cascade of amide activation, nucleophilic cyclization, ...
Synthesis of the tetracyclic core of daphnilactone B-type and yuzurimine-type alkaloid
Abstract: The core of daphnilactone B-type and yuzurimine-type alkaloids was synthesized in only 16 steps from a known β-allyl-γ-butyrolactone. The key sequence of Vilsmeier–Haack cyclization and intramolecular azomethine ...
