    • Isotactic poly(glycidyl nitrate) useful in solid propellants is produced by polymerizing chiral (R) glycidyl nitrate or its enantiomer, (S) glycidyl nitrate. Chiral (R) glycidyl nitrate or its enantiomer is prepared by sequential treatment of chiral (S) glycidyl tosylate or its enantiomer with nitric acid and sodium hydroxide. Chiral (S) glycidyl tosylate or its enantiomer, (R) glycidyl tosylate, can be produced by Sharpless epoxidation of allyl alcohol or by direct tosylation of commercially available chiral glycidol. Likewise, chiral (R) glycidyl nitrate or its enantiomer, (S) glycidyl nitrate, can be prepared directly via nitration of (S) or (R) glycidol, respectively.
    • 可用于固体推进剂的全同立构聚(缩水甘油基硝酸盐)是通过聚合手性(R)缩水甘油基硝酸酯或其对映异构体(S)硝酸缩水甘油酯来制备的。 手性缩水甘油基硝酸酯或其对映异构体通过用硝酸和氢氧化钠顺序处理手性(S)缩水甘油基甲苯磺酸酯或其对映异构体来制备。 手性(S)缩水甘油甲苯磺酸酯或其对映异构体,(R)缩水甘油甲苯磺酸酯可以通过烯丙醇的无稀释环氧化或通过商业上可获得的手性缩水甘油直接甲硅烷基化来制备。 同样地,硝酸N-手性(R)缩水甘油酯或其对映异构体(S)硝酸缩水甘油酯可以分别通过(S)或(R)缩水甘油硝化来直接制备。
