Lithium t-butyl-N-tosyloxycarbamate (LiBTOC) has been found to be an electrophilic aminating reagent. This species reacts with organometallic reagents, ester enolates and α-cuprophosphonates to provide primary amines as well as α-aminocarboxylic and phosphonic esters in their N-(Boc) protected form. (35–80 % isolated yields).
已经发现叔丁基-N-甲苯磺酰氧基氨基甲酸锂(LiBTOC)是一种亲电胺化试剂。该物质与有机金属试剂,酯烯酸酯和α-环丙膦酸酯反应,以提供伯胺以及N-(Boc)保护形式的α-氨基羧酸酯和膦酸酯。(孤立产率为35–80%)。
