A Mannich–Michael combo: An efficient and highly enantioselective cascade process by H‐bonding catalysis for the synthesis of functionalized tetrahydroquinolines has been developed. An indane amine‐thiourea small molecule has been discovered to catalyze this process in high yields and with good diastereomeric ratios and excellent enantioselectivities (see scheme).
Mannich-Michael组合:已开发出一种通过H键催化合成功能化四氢喹啉的高效对映选择性级联方法。已经发现,茚满胺-硫脲小分子可以高收率,良好的非对映体比率和出色的对映选择性来催化该过程(参见方案)。
