3-O-didecanoylglycerol compounds were prepared – starting from a C-4 chiral synthon, 3-buten-1,2-diol – and treated with n-pentylphosphonic dichloride and p-nitrophenol to afford the corresponding diastereomeric phosphonates, which were acylglycerol analogs. Subsequent separation of each of the phosphonate diastereomers A/B or ent-A/ent-B, performed by HPLC, led to four enantiopure stereoisomers that will be
膦酸酯化合物通过与催化丝氨酸形成共价键来模拟在天然底物的酶促羧酸酯水解过程中发生的第一个过渡态。然而,迄今为止,用于抑制研究的有机磷化合物或多或少类似于天然甘油三酯底物。为了阐明脂肪酶的界面活化和作用机制,需要制备特异性抑制剂。为了实现这一目标,从 C-4 手性合成子、3-丁烯-1,2-二醇开始,制备了对映体纯的 sn-1,2- 和 sn-2,3-O-二癸酰基甘油化合物,并用 n -戊基膦酰二氯和对硝基苯酚得到相应的非对映膦酸酯,它们是酰基甘油类似物。随后分离每种膦酸酯非对映异构体 A/B 或 ent-A/ent-B,
