A variety of trans-β-substituted cyclic alcohols were stereoselectively chlorinated to either the corresponding cis-chloride or trans-chloride (inversion or retention of configuration) with good to excellent yields; the stereochemical outcome is determined by the size of the ring and the nature of the β-substituents, especially the electronegativity of the substituted atom.
多种反式-β-取代

氯化物(构型翻转或保留),产率良好至优秀;立体
化学结果取决于环的大小和β-取代基的性质,特别是取代原子的电负性。
