The first asymmetric total synthesis of the putative structure of diplopyrone was achieved in 17 linear steps starting from cis-1,4-butene-diol. The synthetic route features iodine-catalyzed tandem isomerization followed by C-O and C-C bond formation reac
Stereodivergent synthesis of piperidine iminosugars 1-deoxy-D-nojirimycin and 1-deoxy-D-altronojirimycin

A stereodivergent approach for producing piperidine iminosugars has been developed employing a common optically active precursor. The key steps of the synthetic pathway are the double diastereoselection in the asymmetric dihydroxylation of the suitable ch

(Chemical Equation Presented) The enantiomerically pure 5/5-spiroketal required for the synthesis of the ritterazines has been prepared with high diastereocontrol by ring closure followed by equilibration.
Diastereoface differentiation in addition of lithium enolates to chiral α, β-epoxyaldehydes

The aldolisation reaction of lithium ester enolates with chiral α,β-epoxyaldehydes 2a-2f has been investigated. The reaction proceeds with diastereofacial preference in favour of the anti isomer (anti: syn ≈ 4:1) and can be greatly enhanced in the case of
A Stereochemically General Synthesis of 2-Deoxyhexoses via the Asymmetric Allylboration of 2,3-Epoxy Aldehydes
Roush, William R.,Straub, Julie A.,VanNieuwenhze, Michael S.
, p. 1636 - 1648 (2007/10/02)
A stereochemically general strategy for the synthesis of 2-deoxyhexoses is described.This new approach involves the asymmetric allylboration of epoxy aldehydes 12 and 13, prepared via the Sharpless asymmetric epoxidation reaction, as a means of establishi
