product with p-nitrobenzoyl chloride yields (2S)-glycidol p-nitrobenzoate (4) and trans-cinnamyl p-nitrobenzoate (6) in a ratio of 1:1.5. The reaction of (R)Si-(2R,3R)- or (R)Si-(2S,3S)-3-[(methyl)(phenyl)(1-naphthyl)silyl]-glycidols, 7 or 8 respectively, with n-Bu4NF·3H2O affords mixtures of the respective glycidol, trans-cinnamyl alcohol and 3-(1-naphthyl)allyl alcohol. No significant difference in
(2 R,3 R)-3-(三苯基甲硅烷基)缩水甘油(1)与n -Bu 4 NF·3H 2 O在THF中的反应,然后用对硝基苯甲酰氯处理产物,得到(2 S)-缩水甘油对硝基苯甲酸酯(4)和反式肉桂基对硝基苯甲酸酯(6)的比例为1:1.5。的反应([R)Si-所示(2R,3R) -或(- [R)Si-所示(2S, 3小号)-3 - [(甲基)(苯基)(1-萘基)甲硅烷基] -glycidols,7或如图8所示,分别用n -Bu 4 NF·3H 2 O得到缩水甘油,反式肉桂醇和3-(1-萘基)烯丙基醇的混合物。在这两种非对映异构体的反应中产物分布中没有观察到显着差异。
