Abstract
The trichlorolanthanoid (LnCl3)/Zn system has been found to cause cyclodimerization of chalcone to give cyclopentanol derivatives (1 and 2) in both high yields and selectivities (1/2 ratio) compared with the reaction by Yb metal alone. Of trichlorolanthanoids the chlorides of Yb and Eu or Sm showed maximum yields and selectivities (1/2).Keywords
