six steps with a high overall yield (59%). The key-step of the described procedure is the stereocontrolled ringopening of a conveniently functionalized 3-oxonorborn-1-yl triflate under a straightforward basic hydrolysis. The described route constitutes a model procedure for the preparation of other enantiopure C2-substituted 3-oxocyclopentanecarboxylic acids; which are related with the sarkomycin
