converted into the corresponding fluorohydrins FCH2CH(OH)CH2OX by reaction with catalytic amounts of Bu4N+H2F3- and a molar excess of KHF2. Most of the protective groups (X) examined are stable under the above conditions, moreover stereogenic carbons are not affected.
许多ø -保护的缩水甘油被区域选择性地转化成相应的fluorohydrins FCH 2 CH(OH)CH 2用的卜催化量的反应OX 4 Ñ + ħ 2 ˚F 3 -和摩尔过量的KHF 2。所检查的大多数保护基(X)在上述条件下都是稳定的,而且立体碳不受影响。
