An optically pure glyceride analogue in which the 2-O-ester grouping has been reversed was efficiently synthesised from (S)-di-O-isopropylideneglycerol by a sequence that featured an SN2 displacement by the anion of diethyl malonate on a protected glycerol 2-O-triflate.
由(S)-二-O-异亚丙基甘油通过具有被保护的甘油上的丙二酸二乙酯的阴离子置换为S N 2的序列,由(S)-二-O-异亚丙基甘油有效地合成了其中2- O-酯基团被反转的光学纯的甘油酯类似物2- O-三氟甲磺酸。
