The First Synthesis of Sessiline

Abstract: Sessiline is an alkaloid which was recently isolated from the fruits of Acanthopanax sessiliflorus. The molecule contains two five-membered heterocyclic units joined together by an acylaminocarbinol-ether type bond. Here, we describe the first, simple synthesis of sessiline from 5-hydroxypyrrolidin-2-one and 5-hydroxymethylfurfural, which are prepared from succinimide and furfuryl alcohol, respectively. The coupling reaction takes place on moderate heating under neat conditions.

“…Synthesis of Pichiafuran C Sessiline, an alkaloid isolated from the fruits of Acanthopanax sessiliflorus was prepared in 54% yield in neat conditions by reaction of 5-HMF with amidocarbinol 116 (obtained in 3 steps and 28% yield from succinimide). [145] The proposed mechanism is the nucleophilic addition of HMF onto the iminium intermediate, which is in equilibrium with the amidocarbinol (Scheme 46).…”

“…Ugyancsak az acilaminokarbinolok kémiájában szerzett tapasztalatokat alkalmazták a szesszilin (22) elsõ szintézise során. 24 A szesszilin alkaloidot a Acanthopanax sessiliflorus gyümölcsébõl izolálták 2002-ben. 25 A molekula két 5 tagú heterociklusból áll, amelyek egy acilaminokarbinol-éter típusú kötéssel kapcsolódnak.…”
