Abstract
A one-pot procedure has been developed for the synthesis of ethyl 1-hydroxycyclopentanecarboxylates. The procedure includes cycloalumination of terminal olefins with triethylaluminum in the presence of Cp2ZrCl2, reaction of alkyl-substituted aluminacyclopentanes formed in situ with diethyl oxalate in the presence of a catalytic amount of copper salt, and acid hydrolysis.
