✦ Synopsis

Vinylogous iminium salts from g-aminoenamines react with triethylphosphite to aord amino phosphonates in moderate to good yields. The latter are easily converted to a-substituted aminoallylphosphonates that can yield a-substituted aminoallylphosphonates on reaction with butyllitium and a series of electrophiles.
