Optimization of a Pd-catalyzed intramolecular α-arylation synthesis of tricyclo-[7.3.1.02,7]-trideca-2,4,6-trien-13-ones
摘要:
We have optimized the Pd-catalyzed intramolecular alpha-arylation of 2-(2-halo-benzyl)-cyclohexanones and found that the use of 2-(clicyclohexylphosphino)-2',4',6'-tri-t-plopyl-1,1'-biphenyl (X-Phos) as an added ligand led to a reproducible, efficient, and scalable synthesis of tricycle-[7 3 1 0(2 7)]-trideca-2,4,6-trien-13-ones (C) 2010 Elsevier Ltd All rights reserved
