method for the highly diastereoselective preparation of anti tertiary homoallylic alcohols has been developed. The reaction of allyltitanocenes, generated by the reductive titanation of various allylic substrates with a titanocene(II) species, with a variety of ketones produced the anti tertiary homoallylic alcohols in good diastereoselectivity, even when using sterically less congested ketones (see scheme;
用更少的资源不足的一个途径:对的高立体选择性制备的一种实用方法抗第三高烯丙醇已经研制成功。由各种烯丙基底物与钛茂(II)物种进行还原钛化反应生成的烯丙基钛茂与各种酮的反应也产生了具有良好非对映选择性的抗叔均烯醇,即使在使用空间上较不拥挤的酮时也是如此(参见方案; Cp:环戊二烯基; Piv:新戊酰基)。
