enantioselective synthesis of highly functionalized cyclohepta[b]indoles with high enantioselectivity (up to 96% ee). The process combines an enantioselective organocatalytic Michael addition and a highly efficient double Friedel–Crafts reaction sequence in one pot with good yields and stereoselectivity. The structures and absolute configurations of the products were confirmed by X-ray analysis.
已开发出一种新方法,用于对映选择性合成具有高对映选择性(最高ee为96%)的高度官能化的环庚[ b ]
吲哚。该方法在一锅中结合了对映选择性有机催化迈克尔加成反应和高效的双重Friedel-Crafts反应顺序,并具有良好的收率和立体选择性。通过X射线分析确认了产物的结构和绝对构型。
