ABSTRACT
Trialkylphosphine organocatalysis has enabled the regioselective anti-carboboration of alkynoates with 9-BBN-based 1,1-diborylalkanes to produce secondary allylboranes with ß-alkoxycarbonyl and γ-boryl substituents. The utility of the densely functionalized allylboranes was demonstrated by the highly diastereoselective allylation of N-(trimethylsilyl)aldimines to produce homoallylamines containing tertiary allylborane and acrylate moieties.
