On the Synthesis of Tiliacora Alkaloids, II: Synthesis of the Asymmetrical Biphenyl Derivative
Pachaly, Peter,Schaefer, Michael

The biphenyl derivatives S-1 and S-3 were obtained by mixed Ullmann reaction of the phenylacetic esters 3, 4 and 5.Because they contain selectively removable protective groups for the carboxyl functions, S-1 and S-3 are proper intermediates for the constitution selective reaction with the former described asymmetrical dibenzo-1,4-dioxin derivative K.
