Nucleophilic addition of Lewis acid complexed α-amino carbanions to arynes: Synthesis of 1-aryl- N -methyl-1,2,3,4-tetrahydroisoquinolines

Singh, Kamal Nain,Singh, Paramjit,Sharma, Esha,Deol, Yadwinder Singh

, p. 1739 - 1750 (2014/07/08)

The direct C-1 arylation of N-methyl-1,2,3,4-tetrahydroisoquinolines via coupling of α-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. Georg Thieme Verlag Stuttgart New York.
