The preparation and dihydroxylation (OsO4) of a series of conformationally constrained allylic alcohols is described. By using dichloromethane as solvent, the selectivity that favours the anti triol is substantially reduced by hydrogen-bonding effects. This principle is applied to the stereoselective synthesis of syn tetraols from the oxidation of (1S,2S)-1,2-dihydroxy-3-bromo-3,5-cyclohexadiene.
描述了一系列构象受限的烯丙基醇的制备和二羟基化(OsO 4)。通过使用二氯甲烷作为溶剂,有利于抗三醇的选择性通过氢键作用而大大降低。该原理适用于从(1S,2S)-1,2-二羟基-3-溴-3,5-环己二烯的氧化反应合成四元醇的立体选择性合成。
