synthesis of functionalized tetrahydroquinolines with useful biological properties has been developed by means of asymmetric organocatalytic aza-Michael/Michael cascade reactions of nitroolefins with N-protected 2-aminophenyl α,β-unsaturated esters in the presence of a chiral thiourea catalyst. The reaction gave the corresponding highly functionalized tetrahydroquinolines in good yields, excellent
摘要 通过在手性硫脲催化剂存在下硝基烯烃与N-保护的2-氨基苯基α,β-不饱和酯的不对称有机催化aza-Michael / Michael级联反应,开发了具有有用生物学特性的功能化四氢喹啉的高度对映选择性合成。该反应以良好的收率,优异的非对映选择性(> 30:1 dr)和高对映选择性(≤99%ee)得到相应的高度官能化的四氢喹啉。 通过在手性硫脲催化剂存在下硝基烯烃与N-保护的2-氨基苯基α,β-不饱和酯的不对称有机催化aza-Michael / Michael级联反应,开发了具有有用生物学特性的功能化四氢喹啉的高度对映选择性合成。该反应以良好的收率,优异的非对映选择性(> 30:1 dr)和高对映选择性(≤99%ee)得到相应的高度官能化的四氢喹啉。
