Participants

Reaction Steps

A mixture of 1,3-di-O-(n-hexadecyl)-2-O-(2-cyanoethyl)-glycerol (4.8 g., 8.1 mmoles), concentrated hydrochloric acid (50 ml.) and formic acid (50 ml.) was stirred for 16 hours at reflux, then cooled and extracted with ether (3×100 ml.). The combined ether extract was washed with water (200 ml.), dried (MgSO4), filtered and evaporated in vacuo to yield 1,3-di-O-(n-hexadecyl)-2-O-(2-carboxyethyl)-glycerol solids (4.5 g.), which were purified by silica gel chromatography (elution with toluene:ethanol) [3.5 g., 71% yield, m.p. 43°-45° C., ir (CHCl3) 1740 cm-1, n.m.r. (CDCl3) δ 3.93 (t, J=6 Hz, 2, --OCH2CH2COOH) and 2.65 (t, J=6 Hz, 2, --OCH2CH2COOH)].
