The synthesis of a Miltochrista calamine sex pheromone and its diastereomer has been developed. The key steps of the synthetic approach involved Evans' chiral auxiliaries and the addition of alkyne to aldehyde, which were firstly applied to prepare this sex pheromone and its diastereomer. The synthetic sex pheromone could be used to trap insects and study physiological and ecological questions of the lichen moth.

A new class of malolactonate polymers and copolymers were synthesized, starting from the corresponding lactones, and then characterized. Different lateral groups were selected for these polyesters to achieve a wide range of materials characteristics and possible biological recognition. The monomers were prepared according to two established procedures, which gave rather good overall yields. The polymers were obtained by the anionic ring-opening polymerization of the corresponding four-member ring monomers in the presence of a quaternary ammonium salt as the initiator. Final macromolecular and thermal characteristics were in agreement with the designed monomer structures. Molecular weights in the range 4-20 kDa were obtained, as a result of chain transfer reactions. The prepared polyesters displayed stability up to 200°C, and, when tested in preliminary cell culture experiments, provided indications for future applications in the biomedical field.
Emergence of a novel catalytic radical reaction: Titanocene-catalyzed reductive opening of epoxides

The preparatively important catalytic opening of epoxides to β-titanoxy radicals via single-electron transfer (SET) is described. These radicals can be reduced to alcohols or participate in C-C bond-forming reactions. A key step in the catalytic cycle is the conceptually novel protonation of titanium-oxygen and -carbon bonds. Our method combines the advantages of radical reactions, e.g., high functional group tolerance and stability of radicals under protic conditions, with the ability of organometallic complexes to determine the course of transformations in reagent-controlled reactions.
