Highly stable, enantiomerically pure cyclopropylboronic esters are desirable building blocks for the preparation of a plethora of different cyclopropane derivatives. Whereas trans-configured compounds proved to be readily available, we herein report the first synthesis of the corresponding cis-cyclopropanes. The scope and limitation of this process will be discussed. The absolute configuration of the
高度稳定的对映体纯环丙基硼酸酯是制备大量不同环丙烷衍生物的理想结构单元。虽然反式构型化合物被证明是容易获得的,但我们在此报告了相应顺式环丙烷的首次合成。将讨论此过程的范围和限制。产品的绝对构型可以通过化学和光谱相关来确定。
