Synthesis of Furano‐Epothilone D
Chemistry – A European Journal, 2004AbstractThe total synthesis of furano‐epothilone D by a convergent route is reported. The key fragments are available on a large scale to provide sufficient material for biological evaluation. The approach involves a palladium‐catalyzed coupling that generates a highly functionalized aldehyde which is connected in a stereoselective aldol reaction to ...

Enzymatic hydrolysis of poly(ethylene furanoate)
Journal of Biotechnology, 2016The urgency of producing new environmentally-friendly polyesters strongly enhanced the development of bio-based poly(ethylene furanoate) (PEF) as an alternative to plastics like poly(ethylene terephthalate) (PET) for applications that include food packaging, personal and home care containers and thermoforming equipment.

Synthesis of Bifunctional Furano-Allocolchicinoids
Synthesis, 2017An efficient seven-step semisynthetic approach towards non-racemic bifunctional furano-allocolchicinoids, starting from naturally occurring colchicine is presented. The Pd-catalyzed domino Sonogashira coupling/5-endo-dig cyclization was employed as the key step. The prepared compounds exhibited substantial cytotoxicity against T3M4, MiaPaCa-2, Colo-357,
