英文摘要 | Treatment of a catalytic amount of DBC (20 mol%) with a mixture of diethyl 3-cyanoallylphosphonate 1 and N-tosylsulfonylimines 2 gave diethyl 3-cyanobuta-1,3-dienylphosphonates 3 in 72-83% yields.All the products(3a-3H) are assigned 1E,3Z configurations on the basis of the crystal structure of diethyl(1E,3Z)-3-cyano-4-naphthylbuta-1,3-dienylphosphonate (3h), the proton NMR spectra and the proposed reaction mechanism. |
