Owing to the prevalence of this structural motif in biologically active natural and non-natural compounds, a number of methods for the stereoselective synthesis of THF-diols have been developed. Strategically, the stereochemistry is often established in an initial chemical transformation (...
The disruptors were identified as isomeric mixtures of tetrahydrofurandiols (THF-diols; 9,12-oxy-10,13-dihydroxyoctadecanoic acid and 10,13-oxy-9,12-dihydroxyoctadecanoic acid) and leukotoxindiols (LTX-diols; 9,10-dihydroxy-12-octadecenoic acid and 12,13-dihydroxy-9-octadecenoic acid). The ...
l-Serine methyl ester hydrochloride was converted to (S)-2-[N-(benzyloxycarbonyl)amino]-3-(tert-butyldimethylsiloxy)propanal (6). Homocoupling of 6 promoted by [V2Cl3(THF)6]2[Zn2Cl6] (1) gave C2-symmetric diol (7). After manipulation of ... Min,Kang,Jeonghan,... - 《Journal...

In general, the process involves: a) generating a tetrahydrofuran-2,5-diyl-bis(methylene)-bis(sulfonate) from bHMTHFs using a sulfonate; b) displacing nucleophilically at least a sulfonate leaving group from the tetrahydrofuran-2,5-diyl-bis(methylene)-bis(sulfonate) to form a THF-dinitrile; ...
