A highly efficient enantioselective [1,3] O-to-C rearrangement of racemic vinyl ethers that operates under mild conditions was developed. This method with chiral ferrous complex catalyst provided an efficient access to a wide range of chromanols with high yields and excellent enantioselectivities. In addition, an important urological drug (R)-tolterodine and others were easily obtained after simple
开发了在温和条件下运行的高效外消旋乙烯基醚的对映体选择性[1,3] O-C重排。使用手性亚铁配合物催化剂的该方法可高效获得各种色酚,产率高且对映选择性优异。另外,通过简单的转化,很容易获得重要的泌尿科药物(R)-托特罗定等。
