[reaction: see text] Via an X-ray analysis, the sulfonamide bearing R(1) = i-Pr, R(2) = Me, and R(3) = Me is shown to be a tridentate ligand to a Cr(III) salt. This class of ligands, represented by R(1) = t-Bu, R(2) = 2-naphthyl, and R(3) = Me, is effective to achieve an asymmetric Ni/Cr-mediated coupling reaction and, with the C14-C38 segment of halichondrins, its synthetic potential has been demonstrated
[反应:查看文本]通过X射线分析,显示带有R(1)= i-Pr,R(2)= Me和R(3)= Me的磺酰胺是Cr(三)盐。这类配体由R(1)= t-Bu,R(2)= 2-萘基和R(3)= Me表示,可以有效地实现不对称的Ni / Cr介导的偶联反应,并且葫芦素的C14-C38节段,已证明其合成潜力。为该过程提出了一种可能的机制。
