Highly Branched polyprenols, (6E)-2-[(2E)-3,7-dimethyl-2,6-octadienyl]-7,11-dimethyl-3-methylene-6,10-dodecadien-1-ol and (6E,10E)-2-[(2E,6E)-3,7,11-trimethyl-2,6,10-dodecatrienyl]-7,11,15-trimethyl-3-methylene-6,10,14-hexadecatrien-1-ol}, were synthesized (1) from diethyl malate, geranyl bromide, and homogeranyl iodide, and (2) from ethyl acetoacetate and geranyl (or farnesyl) bromide. These alcohols were transformed into disodium phosphates, which have been postulated to be primitive lipids in the evolution of membranes.
高度支化的聚戊烯醇,(6E)-2-[(2E)-3,7-二甲基-2,6-辛二烯基]-7,11-二甲基-3-亚甲基-6,10-十二碳二烯-1-醇和(6E,10E)-2-[(2E,6E)-3,7,11-三甲基-2,6,10-十二碳三烯基]-7,11,15-三甲基-3-亚甲基-6,10,14- hexadecatrien-1-ol} 是由 (1) 从苹果酸二乙酯、香叶基溴和高香叶基碘合成的,以及 (2) 从乙基乙酰乙酸酯和香叶基(或法尼基)溴化物。这些醇被转化为磷酸二钠,人们认为磷酸二钠是膜进化过程中的原始脂质。
