Tk. Yang et al., APPLICATION OF ELECTRO-OXIDATIVE ALPHA-CYANATION OF AZA-RINGS TO THE SYNTHESIS OF GEPHYROTOXIN-223AB, Heterocycles, 38(8), 1994, pp. 1711-1715
Six and five-membered cyclic alpha-cyanoamines have been prepared effi
ciently from N-benzylpiperidine and N-benzylpyrrolidine. These alpha-c
yanoamines were successfully used in the synthesis of gephyrotoxin 223
AB.
