A number of bicyclic macrolides with two stereogenic centres formally derived from ω-cycloalkyl fatty acids were synthesised by ring enlargement of cycloalkanones with novel chiralbuildingblocks, easily available from yeast reduction products of β-keto esters. A comparison with structurally related monocyclic macrolides revealed surprising effects of structural variations on the olfactory properties

The intramolecular protective group (benzylidene acetal) assisted syn-1,3-diol synthesis has been efficiently utilized in a short synthesis of 6-epiprelactone-V starting from (S)-malic acid.
The absolute configuration of 2,4-dimethyl-5-hexanolide, which was found on a nanogram-scale in different Camponotus species as a trail pheromone, is determined by the combination of synthetic methods with electrophysiological and behavior tests. In five different species the same absolute configuration (2S,4R,5S) 3 was found.
