A systematic investigation of the reduction and Grignard reagents addition to 1,4-diketones derived from tartaric acid was carried out. It was found that the reduction proceeded with high selectivity using K-Selectride as the reducing agent; while Grignard reagent addition was highly dependent on structure of the dione as well as on the Grignard reagent. The resultant 1,4-diols represent a series of novel TADDOL analogues.

酒石酸衍生的 1,4-二酮的还原和
格氏试剂添加进行了系统研究。研究发现,使用 K-选择性
氮化物作为还原剂,还原过程具有很高的选择性;而
格氏试剂的加成则高度依赖于二酮的结构以及
格氏试剂。由此产生的 1,4 二醇代表了一系列新型 TADDOL 类似物。
