Bis(oxazoline)-palladium(II) catalyzed carbonylation of homopropargyl alcohols afforded acyclic methoxyacrylate 2 and 6-membered lactone 3a-k in good combined yield. In the case of propargyl alcohols, 5-membered lactones 3p, 3q, 16 were obtained in moderate yields. The one-pot synthesis of kawa lactones 3a, 3r, 3s and formal synthesis of dihydroxycystothiazole A and dihydroxycystothiazole C are presented. To elucidate the stereochemistry of (+)-annularin G and (-)-annularin H, the first asymmetric syntheses of these natural products were achieved.

The homogeneous ruthenium-catalyzed hydrogénation of new symmetrical 1, 3-diketones has been achieved with various ligands including SKEWPHOS and Me-DuPHOS. Complete conversions with enantiomeric and diastereomeric excesses up to 99% were obtained. This represents a new catalytic application of the chiral ligands above. Thieme Stuttgart.
Optically Pure 1,3-Diols from (2R,4R)- and (2S,4S)-1,2:4,5-Diepoxypentane
