Diastereoselective synthesis of all eight L-hexoses from L-ascorbic acid
Ermolenko, Ludmila,Sasaki, N. Andre
, p. 693 - 703 (2007/10/03)
A novel versatile method for the synthesis of all eight diastereomerically pure L-hexoses was developed. L-Ascorbic acid was converted to two diastereomers A. These α-hydroxy esters were transformed into four γ-alkoxy- α,β-unsaturated esters C via the int
