Synthesis of 1,2-Diamine Derivatives Using a Rhodium Catalyst

Du Bois et al. have reported the 1,2-diamination reactions of alkenes using a rhodium catalyst. According to their results, aziridines 2 are formed from alkenes and a sulfamide 1 by the Rh2(esp)2 catalyst and iodobenzene diacetate-promoted aziridination. By adding sodium iodide, the aziridines 2 are cleaved to form the acyclic intermediate 3 and the consequent ring-closing process affords the 5-membered cyclic sulfamides 4. The given sulfamides 4 are hydrolyzed by an aqueous pyridine and converted to the mono Boc-protected 1,2-diamines. In this synthetic process, the tandem ring-opening and ring-closing reactions proceed involving two SN2 type substitutions. Therefore, when E alkenes are used as starting materials, trans-1,2-diamines are given, and in the case of Z alkenes, cis-1,2-diamine derivatives are given, respectively.


Product Highlight

Acetamidoxime: A Useful Reagent for Constructing Heterocyclic Compounds

Acetamidoxime (1) is a useful reagent for constructing heterocyclic compounds by the condensation-cyclization reactions with carbonyl compounds such as carboxylic acids and acid chlorides. For example, an ester 2 is formed by the condensation reaction of the hydroxy group of 1 with the carboxylic acid, followed by the intramolecular cycloaddition of the amino group of 2 to the carbonyl group to give the heterocycle 3. The formed 1,2,4-oxadiazole derivative acts as a bioisostere of the ester and amide groups. Therefore, 1 is expected to be used for the formation of heterocyclic compounds aimed for drug discovery.
