Abstract
Alkylation of amine-alkyl(C-allcoxy-N-ethylcyano)borane with Et(3)OBF( 4) resulted in the isolation of amine-alkyl(C-alkoxy-N,N-diethyrcyano) borane tetrafluoroborates, which, upon aqueous base hydrolysis, yielde d both the amine-alkyl(C-alkoxycarbonyl)borane and the amine-alkyl(N,N -diethylcarbamoyl)borane in varyng ratios. Amine-alkyl(C-alkoxycarbony l)boranes (amine = quinuclidine, pyridine; alkyl = iBu, iPr, sBu; alko xy R = Me, benzyl) representative of several amino acid analogues have been isolated and characterized. These are the first ester derivative s of a boron analog other than glycine.
