A stereoselective synthesis of 1,2-hydroxyalkyl moieties is described herein. These valuable building blocks are obtained with complete regiocontrol and excellent stereocontrol both for the syn or the anti products, by choosing the appropriate enantiomer of the ligand in a copper-catalyzed asymmetric allylic alkylation of delta-alkoxy-substituted allyl bromides.
本文描述了1,2-羟烷基部分的立体选择性合成。通过在δ-烷氧基取代的烯丙基溴的铜催化的不对称烯丙基烷基化反应中选择合适的配体对映体,可以获得对顺式或反式产物具有完全的区域控制和出色的立体控制性的这些有价值的结构单元。
