| Abstract: | The coupling reaction of 3,4,6‐tri‐O‐acetyl‐α‐d‐glucopyranoside 2‐O‐lactone 1 (α‐CMGL) with two kinds of lipophilic amines, aminosteroids and fatty amines, efficiently yielded, after deprotection, the corresponding free α‐glucolipid amides. The latter family of compounds exhibited good thermal stability, allowing the higher homologs having longer linear fatty chains or saturated steroids to possess lamellar smectic A phases. |
