reaction of chiral allenyltitaniums, generated from optically active secondary propargyl phosphates and a Ti(O-i-Pr)4/2 i-PrMgCl reagent, with trialkylstannyl chloride proceeded with a high chirality transfer of more than 93% to afford optically active secondary propargylstannanes in excellent yield, and which, in turn, were converted to optically active (Z)-allylstannanes by reaction with Ti(O-i-Pr)4/2
手性allenyltitaniums的反应中,从光学活性仲炔丙基磷酸盐和Ti产生(O-我-Pr)4 /2我-PrMgCl试剂,与三烷基甲锡氯化物与超过93%的高手性转移的进行,得到光学活性仲propargylstannanes在良好的产率,并且其又被转化为光学活性的(ż)通过用的Ti(O-反应-allylstannanes我-Pr)4 /2我-PrMgCl和下面的水解。
