Description
Summary:A novel and green route for the synthesis of cyclopentane-1,3-diamine ( CPDA ) from hemicellulosic feedstock is established in this work. Through many explorations and optimizations, the single successful multi-step synthesis was found to comprise: (1) the Piancatelli rearrangement of furfuryl alcohol to 4-hydroxycyclopent-2-enone ( 4-HCP ), (2) a highly improved isomerization of 4-HCP into cyclopentane-1,3-dione ( CPDO ) using the Ru Shvo catalyst, (3) conversion of CPDO into cyclopentane-1,3-dioxime ( CPDX ), and (4) a mild oxime hydrogenation of CPDX over Rh/C to afford the desired CPDA . In addition, diastereomerically pure cis - and trans -isomers of CPDA were reacted with (A) bio-based lactones, and (B) 5-(hydroxymethyl)furfural (HMF) to synthesize novel bifunctional diol monomers with internal amide and imine groups, respectively. Monomer 5 , derived using γ-valerolactone (GVL), was successfully applied in the synthesis of polyurethanes. Synthesis of cyclopentane-1,3-diamine from hemi-cellulosic origin is established for the first time, with useful chemical insights and potential applications demonstrated.
