Reaction Steps
886 g (2.44 mol) of 2-(triphenyl-phosphanylidene)-propionic acid ethyl ester in methylene chloride (4 L) was added dropwise into a refluxing solution of glycoaldehyde dimer (140 g, 1.17 mol) in methylene chloride (6 L). After refluxing for 4 h, the solvent was evaporated. Resulting crude product was fractionated (bp 108–114° C. at 2 mmHg) to give 304 g (90%) pure product as an oil. 1H-NMR (300 Hz CDCl3) δ 6.88 (t, 1H, CH), 4.35 (d, 2H, CH2OH), 4.20 (q, 2H, OCH2), 1.85 (s, 3H, CH3), 1.30 (t, 3H, CH3).
