    • This invention relates to processes and intermediates for the stereoselective alkylation of carbonyl groups. The invention in particular allows the stereoselective preparation of the antidepressant drug escitalopram. It has been found that boric or boronic acid derivatives are useful bridging elements for the attachment of a chiral group to a compound containing a carbonyl group to be alkylated. The said borates and boronates are thus useful in a process for the asymmetric alkylation of a carbonyl group in a compound containing a carbonyl group and an anchor group capable of reacting with a boric or boronic acid derivative. The asymmetric alkylation can be carried out by admixing the compound containing a carbonyl group to be alkylated and the anchor group capable of reacting with a boric or boronic acid derivative with a boric or boronic acid derivative, adding a chiral alcohol, and adding an organometallic compound. After the alkylation reaction, the borate and boronate can be easily removed by hydrolysis.
    • 本发明涉及羰基的立体选择性烷基化方法和中间体。 本发明特别允许立体选择性制备抗抑郁药物依他普仑。 已经发现硼酸或硼酸衍生物是用于将手性基团连接到含有待烷基化羰基的化合物的有用的桥连元件。 因此,所述硼酸盐和硼酸盐可用于在含有羰基和能够与硼酸或硼酸衍生物反应的锚定基团的化合物中羰基的不对称烷基化方法。 不对称烷基化可以通过将待烷基化的羰基和能够与硼酸或硼酸衍生物反应的锚定基团与硼酸或硼酸衍生物反应,加入手性醇,并加入有机金属化合物 。 在烷基化反应之后,可以通过水解容易地除去硼酸盐和硼酸盐。
