Polymerisation of a terpene-derived lactone: a bio-based alternative to ε-caprolactone

Autor: Matthew D. Jones, Marc Hutchby, Helena C. Quilter, Matthew G. Davidson

Publikováno v: Quilter, H, Hutchby, M, Davidson, M & Jones, M 2017, ' Polymerisation of a terpene-derived lactone: A bio-based alternative to ԑ-caprolactone ', Polymer Chemistry, vol. 8, no. 5, pp. 833-837 . https://doi.org/10.1039/C6PY02033J

A high-yielding 4-step process for converting a naturally occurring terpene, β-pinene, into a substituted e-caprolactone is herein reported. Investigations into the ring-opening polymerisation and copolymerisation of this monomer are also described.

Orthogonally Protected Schöllkopf’s Bis-lactim Ethers for the Asymmetric Synthesis of α-Amino Acid Derivatives and Dipeptide Esters

Autor: Steven D. Bull, Adam C. Sedgwick, Marc Hutchby

Publikováno v: Synthesis. 48:2036-2049

Alkylation of the aza-enolates of orthogonally protected chiral bis-lactim ethers with electrophiles proceeds with good levels of diastereocontrol to afford trans-alkylated adducts that can be efficiently deprotected via hydrolysis/hydrogenation proc

ChemInform Abstract: Orthogonally Protected Schoellkopf′s Bis-Lactim Ethers for the Asymmetric Synthesis of α-Amino Acid Derivatives and Dipeptide Esters

Autor: Marc Hutchby, Steven D. Bull, Adam C. Sedgwick

Publikováno v: ChemInform. 47

A diastereoselective trans-alkylation of aza-enolates of orthogonally protected chiral bis-lactim ethers with electrophiles, such as alkyl halides, and subsequent deprotection via hydrolysis/hydrogenation leads to dipeptide ester derivatives.
