V. Denniel et al., HYDROBORATION OF METHYL 2-ACETAMIDOACRYLATE - CHARACTERIZATION AND NUCLEOPHILIC REACTIVITY OF THE RESULTING OXYTRIORGANOBORATE, Tetrahedron letters, 36(20), 1995, pp. 3507-3510
Hydroboration of methyl 2-acetamidoacrylate with dicyclohexylborane pl
aces boron exclusively at the 2-position. The product is obtained as a
n internal complex whose zwitterionic structure is established by X-ra
y cristallography. Alkali metal salts of this heterocyclic oxytriorgan
oborate are readily alkylated or acylated.
