β,γ-Unsaturated α-aminophosphonates: synthesis and reactivity
摘要:
Vinylogous iminium stilts from gamma-aminoenamines react with triethylphosphite to afford amino phosphonates in moderate to good yields. The latter are easily converted to alpha-substituted aminoallylphosphonates that can yield alpha-substituted aminoallylphosphonates on reaction with butyllitium and a series of electrophiles.
