Synthesis and Reactivity of Boron Heterocycles Derived from Amino Acids

摘要

Several boron heterocycles of the general formula H2NCH (R) C (0) 0B(OH)2 (R = H,-alkyl) have been synthesized by the reaction of an amino acid with boric acid. They have been characterized by elemental analysis, IR and NMR spectra and by converting them to spiro compounds with oxalic acid.
