Abstract : Primary and secondary alkylboranes reacted rapidly at low temperature with Li or K t-butyl-N-tosyloxycarbamate (LiBTOC or KBTOC) to give the corresponding N-Boc protected primary amines in modest to good yields (16–81%). N-Boc primary amines were obtained from the reaction of alkylboranes with Lithium or Potassium salts of t-butyl-N-tosyloxycarbamate.
