We transformed RMgBr into R-Ti derivatives with the production of byproduct MgBrO~(i-Pr at the same time, but we didn\'t need romove the Mg salt by centrifugation or chelating reagents, for bis[2-(N,N-dimethylamino)ethyl] ether could chelate with Mg atom and thereby reduced the Louis acidity of Mg salt, so we used R-Ti derivatives produced in situ to alkylate the aldehydes induced by BINOL-Ti complexes..

我们通过利用TiO~(i-Pr_4使格氏试剂转化成烷基钛，同时产生具有亲核加成促进作用的副产物MgBrO~(i-Pr，由于BDMAEE能与MgBrO~(i--Pr络合降低其路易酸活性，所以不需要离心或者借助络合试剂完全除去镁盐，而使用原位生成的烷基钛在BINOL-Ti诱导下对醛进行不对称加成。
