摘要

Lithium trialkylborohydrides were found to effect rapid monodealkylation of phosphonic diesters, and this reaction was applied to the synthesis of alkylphosphonic acid 2-aminoethyl esters [H2N (CH2) 2OP (OH) R, 4], a little-explored class of analogs of the inhibitory neurotransmitter γ-aminobutyric acid (GABA). Compound 4a (R= Me) proved to be a potent antagonist at human ρ1 GABAC receptors (expressed in Xenopus laevis oocytes), with an ...
