A large-scale (∼100 g) synthesis of symmetrical and unsymmetrical triacylglycerols containg docosahexaenoic acid (D) and two of either lauric (L), palmitic (P) or stearic acid (S) is described. Key improvements in purification of synthetic intermediates, in addition to a more efficient acetonide cleavage reaction affords the six TAGs (LaDLa, LaLaD, PDP, PPD, SDS, SSD) in yields of 80–90% and in regioisomeric
描述了大规模(〜100 g)的对称和不对称三酰基甘油的合成,其中含有二十二碳六烯酸(D)和月桂酸(L),棕榈酸(P)或硬脂酸(S)中的两个。除更有效的乙醛裂解反应外,合成中间体纯化方面的关键改进还提供了六个TAG(LaDLa,LaLaD,PDP,PPD,SDS,SSD),产率为80-90%,区域异构纯度大于或等于90%。
