US-2835565-A chemical patent summary.

The Gabriel reagent is widely used as a nucleophilic aminating agent since its reactivity is reliable and its handling is easy.1) A variety of aminating agents analogous to the Gabriel reagent have been reported. The potassium salt of imide 1 reacts with alkyl halide to give imide 2. 2 is treated with base or acid to give either N-Boc-amine 3 or N-methoxycarbonylamine 4, respectively. Moreover, 1 also serves as an acid nucleophile in the Mitsunobu reaction to allow for the conversion of hydroxy groups to amino groups. Therefore, 1 is a useful reagent to give monoprotected amines.2) Fukuyama and co-workers have demonstrated various reactions using the N-substituted sulfonamide 5.3) Smooth reactions of 5 occur with alkyl halides under basic conditions and alcohols under Mitsunobu conditions to provide o-nitrobenzenesulfonyl (o-Ns) amines 6. The various o-Ns amines (Alloc, Boc, Cbz) 6 obtained from these reactions can be ...
