Abstract

PtI 2-Catalyzed Cyclization of 3-Acyloxy-1,5-enynes with the Elimination of HOAc and a Benzyl Shift: Synthesis of Unsymmetrical m-Terphenyls. -The utility of the method is exemplified by the preparation of a photoelectrically interesting multiphenyl compound [cf. (X)]. The regioselectivity of the reaction is examined by extensive evaluation of its mechanism via DFT-calculations. -(HUANG, K.; KE, X.; WANG, H.; WANG, J.; ZHOU, C.; XU*, X.; LIU, L.; LI, J.; Org.
