Yk. Shim et al., Synthesis of the 6,7-bis(2-methoxycarbonyl(1,1-dideutero)ethyl) derivativeof protoporphyrin IX dimethyl ester, J PORPHYR P, 4(2), 2000, pp. 185-191
A new total synthesis of a protoporphyrin LY derivative in which the a-meth
ylene protons of the 13,17-(2-methoxycarbonylethyl) substituents are regios
electively deuterated is described. The deuterated porphyrin was obtained u
sing the oxidative cyclization of an a,c-biladiene dihydrobromide. Copyrigh
