Title: Pd(II)-catalyzed one-step construction of cycloalkane-fused indoles and its application in formal synthesis of (±)-aspidospermidine. Author: Xia G, Han X, Lu X. Journal: Org Lett; 2014 Apr 04; 16(7):2058-61. PubMed ID: 24650163. Abstract: A highly efficient, redox-free Pd(II)-catalyzed tandem cyclization reaction initiated by intramolecular aminopalladation of alkynes followed by nucleophilic addition to nitriles is developed. This method provides a versatile approach for the synthesis of six- to eight-membered ring-fused indoles in one step and has also shown advantages in the formal synthesis of (±)-aspidospermidine.[Abstract] [Full Text] [Related] [New Search]
