Ursinyova, Nina published the artcileCopper-Catalyzed Borylation of Cyclic Sulfamidates: Access to Enantiomerically Pure (β-and γ-Amino-alkyl)boronic Esters, Recommanded Product: tert-Butyl N-[3-(tetramethyl-1,3,2-dioxaborolan-2-yl)propyl]carbamate, the publication is European Journal of Organic Chemistry (2016), 2016(4), 673-677, database is CAplus.
Cyclic sulfamidates undergo borylation under Cu-catalyzed conditions using B2pin2 to give enantiomerically (and diastereomerically) defined (aminoalkyl)boronic esters. External iodide is essential, but the intermediacy of simple alkyl iodides was excluded; N-sulfated intermediates are key in the borylation sequence. Based on stereochem. studies and trapping experiments, the involvement of C-centered radicals under these Cu-catalyzed conditions appears likely.
