The formation of enantiopure delta-lactones condensed with alicyclic rings has been achieved either by reduction with baker's yeast of the corresponding delta-keto esters and delta-keto acids or by enzymic resolution of the former compounds. The absolute configurations of the lactones were determined by means of CD spectroscopy, using the correlation method. (C) 2000 Elsevier Science Ltd. All rights reserved.
