Reaction between 1,n-Diamines, Diketene, and Dibenzoylacetylene in the Presence of Triphenylphosphine: One-Pot, Pseudo-Five-Component Synthesis of Bisfuramides
Synthesis
DOI: 10.1055/s-0028-1083637
Abstract
Using diketene as a basic reagent, a one-pot, pseudo-five-component
reaction for the synthesis of highly substituted bisfuramides is
described. In this method, ring opening of diketene occurs in mild
condition and without a catalyst. Thus, the reaction between diketene,
1,n-diamine, and dibenzoylacetylene, in the presence of triphenylphosphine,
produces bisfuramides.
