General substrates for stereoselective synthesis: utilization of D- and L-arabinose

Soares, Fábio da Paixão ; Silva, Maria Joselice e ; Doboszewski, Bogdan ;

Abstract:

Carbohydrates are convenient chiral substrates during the stereoselective synthesis since their absolute configurations are known just like the methodologies of their functionalization. Both D- and L-arabinose are particularly interesting as the starting compounds since the same synthetic conditions can be used to obtain the enantiomeric products. Reported here are four procedures of deoxygenation at the position C3 of 5-t-butyldiphenylsilyl-1,2-O-isopropylidene-D- and –L-arabinofuranose 1 and 7, respectively, to obtain 3- deoxy-1,2-O-isopropylidene-D- and L-threopentofuranose 3 and 9, respectively, as the general substrates for further applications.
