Asymmetric Synthesis of 1,4-Disubstituted Tetrahydroioquinolines
摘要:
Bischler-Napieralski cyclisation of optically active beta-substituted phenylethylamines 4a-c followed by diastereoselective reduction led to 1,4-disubstituted tetrahydroisoquinolines 6a-c and 8a-c. The same methodology afforded the 4-benzyl pyrroloisoquinolines 10.
