A concise and stereoselective approach for the total synthesis of (+)-secosyrin 1 and (+)-syributin 1, metabolites of Pseudomonas syringae, is reported. The key synthetic step in this approach is a highly stereoselective construction of spiro center, through a one-pot dehydrohalogenation, intramolecular hetero-Michael addition (IHMA) and ester hydrolysis of halohydrins derived by the ring opening of 1,2-cyclopropanecarboxylated xylal derivative.

A stereoselective methodology was developed for the construction of C-spiro-glycosides in two steps involving bromonium ion activated solvolytic ring opening of sugar derived 1,2-cyclopropanecarboxylates followed by a one-pot dehydrohalogenation, intramolecular hetero-Michael addition (IHMA) and ester hydrolysis. The obtained spirocyclic lactols were further converted to enantiomerically pure spirolactones.

Model studies towards the total synthesis of syringolides using a rhodium-catalyzed intramolecular C-H insertion reaction as the key step are described. A highly stereospecific synthesis of spirolactones is achieved employing this methodology.

The indium-mediated allylation of a protected derivative of D-xylulose in aqueous THF is highly diastereoselective. The obtained product has been converted in four steps into a spiro lactone previously transformed into syributins and secosyrins. This remarkably short reaction sequence constitutes therefore a formal synthesis of these compounds and provides also a promising synthetic approach towards the syringolides.

The first total synthesis of (+)-secosyrin 1, isolated from P. syringae, pv. tomato, was accomplished in a stereoselective manner from diisopropyl D-tartrate. This synthesis unambiguously established the stereochemistry of (+)-secosyrin 1.
