Aqueous Aza-Michael Reaction of Conjugated Alkenes: Toward Spermine

Abstract

An aqueous aza-Michael reaction is efficiently achieved with excellent conversions without any additives. The method works very well on a molar scale with selectively for aliphatic amines. An intermediate for spermine is also made by this green process.

Keywords:

• Aqueous medium
• aza-Michael reaction
• green chemistry
• spermine
