The intermolecular addition of carbon centered radicals to alkenylboranes has been studied. The influence of the olefin and boron substituents on the reactivity and the regioselectivity was determined. Competitive experiments were carried out to estimate the relative reactivity of a series of vinylboranes and other electron deficient alkenes. Intramolecular versions of these additions were also described

Unnatural amino acids were synthesized on solid-phase by reaction of a resin-bound Schiff base with organoboranes. This novel use of a resin-bound glycine cation equivalent allows for the preparation of a variety of amino acid structural types not readily available by the complementary anionic equivalent.
