The partial deuteration of alkynes proceeds via a flow chemistry approach under Lindlar’s heterogeneous catalysis to provide cis-dideuterated olefins in good yields. Further, dideuterated olefin has been successfully utilized for Sharpless asymmetric dihydroxylation followed by Mitsunobu reaction for the synthesis of deuterated taxol side chain.
炔烃的部分氘代反应是通过流化学方法在Lindlar的多相催化下进行的,以高收率提供顺式-氘代烯烃。此外,二氘代烯烃已成功用于Sharpless不对称二羟基化反应,然后经Mitsunobu反应合成氘代紫杉醇侧链。
