Improved E-selectivity in the Wittig reaction of stabilized ylides with alpha-alkoxyaldehydes and sugar lactols.

[reaction: see text]. The Wittig reactions of alpha-alkoxyaldehydes and sugar lactols with stabilized ylides such as (alkoxycarbonylmethylene)triphenylphosphoranes typically proceed with low E-selectivities. However, we have discovered that the reaction o

Diastereoselectivity of the thio-Claisen rearrangement of acyclic precursors bearing a chiral centre adjacent to carbon 6

A number of chiral allylic alcohols have been prepared and submitted to a Mitsunobu reaction with dithioacetic acid. Allyl dithioesters were deprotonated by LDA at -30°C and resulting enethiolates were quenched with iodomethane to afford quantitatively S-

CATALYTIC OSMYLATION OF ELECTRON POOR ALLYLIC ALCOHOLS AND ETHERS. A SYNTHETIC APPROACH TO BRANCHED CHAIN SUGARS

The catalytic osmylation of electron-poor allylic ethers and alcohols was studied.In the case of γ-alkoxy E-enoates reaction selectivity was found to range from 2:1 to 8:1 in favor of the arabino (2,3-syn - 3,4-anti) product, regardless of the double bond

AN OBSERVATION OF DIASTEREOFACE SELECTIVITY IN THERMAL REACTIONS BETWEEN δ-ALKOXYALLYLSTANNANES AND ALDEHYDES

The δ-alkoxyallylstannanes (4) and (5) react stereoselectively on heating with p-nitrobenzaldehyde to provide the homoallylic alcohols (14) - (17), with (14) : (15) = 82 : 18; (16) : (17) = 73 : 27

INTRAMOLECULAR NITRILE OXIDE CYCLOADDITION ON CHIRAL OLEFINS : A STEREOCONTROLLED APPROACH TO β-KETOL PRECURSORS.

The intramolecular nitrile oxide cycloaddition reaction on (E) or (Z) olefins featuring a sulphur atom along the carbon chain connecting dipole and dipolarophile occurs with a poor to excellent anti stereoselectivity, which is mainly affected by the subst

THE REACTION OF CARBOHYDRATE-DERIVED ALKOXYALDEHYDES WITH METHOXYCARBONYLMETHYLENETRIPHENYLPHOSPHORANE: STEREOSELECTIVE SYNTHESIS OF β-UNSATURATED ESTERS

The reaction of several carbohydrate-derived alkoxyaldehydes with methoxycarbonylmethylenetriphenylphosphorane affords α,β-unsaturated esters with Z-stereoselectivity.The stereoselectivity depends on the substrate structure and the nature of the solvent u
