Phosha-Meerwein Reaction of Diazo Esters

Phosha-Meerwein Reaction of Diazo Esters

Diazo esters (la,b) react with trialkyl phosphates (2a-c) in the presence of BF 3 .OEt 2 to give the corresponding phosphates (3a-e) in 42-58 % yields. The competed intra/intermolecular protonation in the reaction of la with dimethyl hydrogen phosphite leads to phosphonate. 4,and phosphite 5.
