Lithium t-butyl-N-tosyloxycarbamate (LiBTOC) has been found to be an electrophilic aminating reagent. This species reacts with organometallic reagents, ester enolates and alpha-cuprophosphonates to provide primary amines as well as alpha-aminocarboxylic and phosphonic esters in their N-(Boc) protected form. (35-80 % isolated yields).
