Boron Analogues of α-Amino Acids: Synthesis and Characterization of Some Amine-methoxycarbonylboranes and Trimethylamine-(alkylcarbamoyl)boranes

Syntheses of a number of amine-methoxycarbonylboranes R2−nHnN·BH2COOCH3 and trimethylamine-(alkylcarbamoyl)boranes, Me3N·BH2CONRR′ are reported. Both types of compounds have been prepared by condensing appropriate amine-carboxyboranes with methanol and an amine, respectively, in presence of dicyclohexylcarbodiimide, and have bean characterized by elemental analysis, IR and NMR (1H and 11B) spectra.
