Nucleophilic Addition of Lewis Acid Complexed α-Amino Carbanions to Arynes: Synthesis of 1-Aryl-N-methyl-1,2,3,4-tetrahydroisoquinolines
摘要:
The direct C-1 arylation of N-methyl-1,2,3,4-tetrahydroisoquinolines via coupling of alpha-amino carbanions derived from Lewis acid complexed tetrahydroisoquinolines and in situ generated arynes is described. This process provides an easy access to the title compounds and a new synthetic route to (+/-)-cryptostyline alkaloids.
