A general and stereospecific homologation strategy for the synthesis of heptopyranosides is reported. The strategy employs the Wittig olefination and proline-catalyzed α-aminoxylation to achieve one carbon elongation and stereoselective hydroxylation at the C6 position, respectively. The l-glycero- and d-glycero-heptopyranosides can be obtained with nearly perfect stereoselectivity. Further study reveals the difference in the chemical shift of the C6 proton of l/d-glycero-heptopyranosyl diastereomers, which is found to be useful for assignment of the configuration of heptopyranosides.

A new compound that is structurally related to the undecose ring structure of herbicidins has been prepared. The synthesis of this novel furanosyl-pyranone derivative was made possible through the regioselective reductive ring-opening of a 3,5-O-benzylidene-D-xylofuranose and the hetero-Diels-Alder reaction of an aldehyde and a Danishefsky-type diene. The highly functionalized pyranone derivative can be a useful precursor for the synthesis of herbicidins.

Wacker oxidation of terminal olefins was carried out at room temperature and atmospheric pressure by using Pd(0)/C in THF/H2O (9:1). Palladium(0)/C was proven to be highly efficient catalyst for the Wacker oxidation of terminal olefins to the corresponding methyl ketones. The catalyst was reusable while maintaining its activity and selectivity to a high degree.

Dhavale, Dilip D.,Chaudhari, Vinod D.,Tilekar, Jayant N.
, p. 7321 - 7323 (2007/10/03)
A practical approach for the synthesis of the (2S,3S,4R)-trihydroxyazepane 1d has been reported. Starting from α-D-xylo-pentodialdose, readily available from D-glucose, the sequence involves Wittig olefination and reductive amination as key steps.
