The diastereo- and enantioselective synthesis of 2,3,4-trisubstituted tetrahydroquinolines has been developed through organocatalytic domino aza-Michael–Michael reaction of o-N-tosylaminophenyl α,β-unsaturated ketones with nitroalkenes. This useful and simple domino process afforded diverse highly functionalized tetrahydroquinolines, some of which are not easily accessible using other methodologies
的2,3,4-三取代的四氢喹啉的diastereo-和对映选择性合成已经通过的有机催化多米诺氮杂迈克尔-反应开发ø - Ñ -tosylaminophenylα,β不饱和酮与硝基烯烃。这种有用且简单的多米诺工艺提供了多种高度官能化的四氢喹啉,其中一些不易使用其他方法获得,收率高且非对映和对映选择性极佳(高达> 30:1 dr,> 99%ee)。
