Phosphatidylcholines. Murakami, Sachiko; Noguchi, Yasuhisa; Konishi, Hidenori (Nippon Oils and Fats Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 61275286 A2 5 Dec 1986 Showa, 5 pp. (Japan) CODEN: JKXXAF. CLASS: ICM: C07F009-10. APPLICATION: JP 85-114328 29 May 1985. DOCUMENT TYPE: Patent CA Section: 33 (Carbohydrates) Title compds (free of metals), were prepd. by mixing glycerophosphorylcholine (I) and fatty acid chlorides or anhydrides (without solvents). 563-24-6 and 24909-72-6 which are cas registry numbers of chemicals are mentioned. Thus, I (prepd. from egg yolk lecithin and 10% Bu4N+OH-) 10, palmitic anhydride 40, and dimethylaminopyridine 19 g were mixed for 5 min and left for 48 h to give 16.0 g phosphatidylcholine dipalmitate. .

Synthesis of carbamyl and ether analogs of phosphatidylcholines

Synthesis of carbamyl and ether analogs of phosphatidylcholines. Agarwal, Kirti; Bali, Anu; Gupta, C. M. (Div. Biophys., Cent. Drug Res. Inst., Lucknow 226001, India). Chem. Phys. Lipids, 36(2), 169-77 (English) 1984. CODEN: CPLIA4. ISSN: 0009-3084. DOCUMENT TYPE: Journal CA Section: 33 (Carbohydrates) Section cross-reference(s): 6, 29, 63 1-O-Hexadecyl-2-O-(heptadec-8-cis-enyl)carbamyl-sn-glycero-3-phosp hocholine (I) was prepd. from 1,2-O-isopropylidene-sn-glycerol in several steps. Each step is simple to perform and gives the desired products in high yield. Also, some of the intermediates formed during the synthesis were efficiently utilized to prep. 1-O-hexadecyl-2-oleyl-sn-glycero-3-phosphocholine, 1-O-hexadecyl-2-oleoyl-sn-glycero-3-phosphocholine and 3-O-hexadecyl-2-oleoyl-sn-glycero-1-phosphocholine.Several substances like 24909-72-6 may be metioned in this study. These phosphatidylcholine analogs are useful for studying the possible role of phospholipases in the capture and lysis of liposomes in vivo. .
